Looking under the hood of Shimano Di2
Welcome back to the CyclingTips Nerd Alert podcast! This week tech editor Dave Rome chats about the things to know with Shimano’s new Di2 12-speed shifting and how it differs from previous generations. And what better guest to speak to about common issues, limitations, fun features, and things to look out for than the Di2 nerd himself, Terry Seidler of BetterShifting.com.

Should more people consider a custom bike instead of a production one?
We finally have our full crew of Nerds back on this week’s episode, and boy, was there a lot to discuss. There’s a new custom bike show in the works for 2023 called Made, which will be based in Portland, Oregon, and will be held outdoors. No one will ever complain about another opportunity to see beautiful custom bikes in person, but are they just eye candy, or should more people actually consider buying one instead of a stock machine? Upstart brand Aerosensor also has a new portable device that claims to deliver aerodynamic drag data in real time, and we wonder what LeBron James’s US$30m investment in Canyon Bicycles will mean moving forward. And seeing as how we finally have Caley back, all of our answers for this week’s Ask a Mechanic segment — naturally — involves a hammer.

Does it matter where your bike is built?
The Nerds are back with a long overdue group show, and they’ve got a lot to talk about! James recaps some of the highlights from the recent Eurobike show in Frankfurt, Dave chats about the pitfalls of modern e-commerce with Silca’s Josh Poertner, we chat about two new road bikes — the Cervelo S5 and the Enve Melee — and debate how much it matters where a bike is manufactured. And finally, after a long hiatus, it’s another round of Ask a Mechanic!

The future of aero wheel development might be a bit rocky
Computational fluid dynamics (CFD) and wind tunnels have long been the primary tools used by wheel engineers and aerodynamicists. However useful they are, though, they’re still based on laminar airflow — those picture-perfect parallel lines you see in illustrations — that doesn’t necessarily reflect real-world conditions. So what happens if you introduce a degree of turbulence to the R&D process? Do things change? Can the wheels get better? And what might this mean for bikes and other gear in general? Buckle up for this one; we’re about to get real nerdy here.

Tech from the Tour paddock
We’re a little late with this week’s Nerd Alert episode and for good reason – the Wi-Fi at the Tour de France is terrible. That’s right, Caley Fretz and Ronan Mc Laughlin are in France and chat about all things Tour de France tech. From prep for the cobbles to bikes with hidden motors (just kidding!), Ronan and Caley catch up with a number of pro riders to hear what they’re riding and why.

Rim brakes aren't dead yet
The bike industry may have shifted entirely to disc brakes, but there are millions of happy rim-brake users out there with bikes that still have years — or even decades — of life left in them. Mainstream brands have already stopped spending money on anything related to rim brakes, and while that’s a bummer in one sense, it’s also created an opportunity for smaller brands to fill the void.

Flat tires and sketchy brakes — it’s Field Test time again!
This week’s episode comes to you live from Steamboat Springs, Colorado, where we’ve assembled four testers and a video team to evaluate ten different bikes. We’ve split them into six gravel and four road models this time around, with a focus on lower-priced options. The full reveal will come a bit later once we’re all done with testing, but let’s just say some of the bikes have already genuinely surprised us with how good they are, while others have made some unforgivable missteps.

Only a crazy person would think we need yet another bike brand, right?
If you’ve got a decent chunk of change and are looking for a higher-end carbon drop-bar bike, there’s certainly no shortage of good options -- and probably too many of them, in fact. So why on earth would someone think it’s a good idea to start yet another one given this hyper-competitive environment? Well, that’s just what the folks at Bridge Bike Works are doing in Toronto, Canada. The company’s first bike sounds interesting enough, but the story behind the brand is arguably more compelling.

So. Many. New. Bikes.
June is turning out to be an exceptionally hot month in terms of new bike releases, and Ronan joins James and Dave as a special guest to help us talk through them all. Although we don't have official information just yet, we know a new Trek Madone, Giant Propel, Canyon Ultimate, and Scott Foil are all likely to be announced within the next few weeks -- and thanks to revamped UCI technical regulations, there's once again some legitimately unique thinking going on in terms of design features. We also dissect Pinarello's new Grevil F gravel race bike, chat about Dave's favorite bikes from the Handmade Bicycle Show Australia, and wrap up with another round of Ask a Mechanic.

Things that shouldn’t break
Modern bikes are marvellous creations that continually push engineering boundaries with a continued focus on lighter, faster, and sleeker. However, that raises a big question, is the bicycle industry flying a little close to the sun when it comes to safety? It’s exactly this concern that this week’s Nerd Alert deep dive episode covers. Join James and Dave, as they speak with world-renowned carbon fibre repair, testing, and inspection expert Raoul Luescher of Melbourne-based Luescher Teknik. The conversation covers existing test standards related to forks, the perceived gaps in those standards, where the industry could (and should) do more, and some helpful hints for safety checking what's arguably the most critical part of your bike at home.

Free the feet!
Riders commonly complain that they can’t find cycling shoes that are wide enough, but when was the last time you heard someone say their shoes are too wide? Maybe that’s a sign cycling footwear should be wider in general. We also chat about the utility of bike-mounted cameras (and radar), what Goodr still needs to do to really shake up the cycling sunglass market, and where to draw the line between buying tools and paying for labor.

A little honesty goes a long way
Roval has finally cleared the air on why its earlier Rapide CLX and Alpinist CLX wheels weren’t tubeless-compatible when they launched in 2020, and while the final outcome is positive, it would’ve been nice if it hadn’t also come with a healthy dose of obfuscation for the past two years. We also give Wilco Kelderman a lesson in how bikes work, speculate about Campagnolo’s mysterious new wheels spotted at the Giro, discuss some new hardware developments at Zwift (or lack thereof, as the case may be), and reveal why you shouldn’t wash your bike like Peter Sagan.

The future of helmet safety
Welcome back to the Nerd Alert podcast! This week we have a deep dive episode about something that’ll likely bring positive change to the helmets we all wear. Our guest is Peter Haldin, the Chief Science Officer and a Co-Founder of MIPS. However, in this interview, Peter is wearing another hat (helmet?) and speaks about his role as the Convener of the Working Group 11 (WG11). In short, WG11 is working to bring rotational-based testing to helmet safety standards, and the goal is to help reduce the number of brain injuries suffered from cycling crashes. Where things get a little confusing is that the likes of Rudy Project and Kask have already started promoting that their helmets meet WG11 test standards. This episode clarifies what this working group is, what the testing involves, and what the future of helmet safety may look like.

To lug or not to lug? That is the question
So much to talk about this week! Colnago's new C68 is more modern-looking than any C-model that came before it, but it's also lost much of what made its predecessors unique. Headset bearings are still a pain to service on modern bikes, though at least they're lasting longer. And what's going on at Wahoo? Caley unfortunately had to skip out for this week's Ask a Mechanic segment, but that's ok; none of the answers required hammers, anyway.

Recycling carbon fiber is no longer a pipe dream
The topic of sustainability and carbon fiber has long been a black eye on the bike industry, but one company in Tennessee — called Carbon Fiber Recycling, of all things — is seemingly turning that around. Old broken frames? Random components? Scrap uncured pre-preg? It’s all good, according to CFR: just stick it all in its magic machine, and usable raw material comes out the other end. Best of all, the process is supposedly quite economical for everyone involved, there’s almost no waste product produced, and the company has plans to ramp things up big-time. Sounds too good to be true? Maybe it is. But maybe it isn’t.

Tubeless domination at Paris-Roubaix, and a look at the state of retail
This year’s Paris-Roubaix was all about tubeless tires and foam inserts — so much so that it’s easier to talk about who wasn’t on them than who was. But the best part of modern Paris-Roubaix tech? The fact that it’s all so normal. The Nerds also bring on the owner of a small brick-and-mortar shop to talk about the state of retail in the bike industry, and then he joins us as a guest wrench on a super fun segment of Ask a Mechanic.

More fun new stuff from Sea Otter, and the future of traveling with your bike
Caley promised to be more prepared for our second Sea Otter episode, but his list of neat new stuff that he found at the show was a little… questionable. Luckily for him, we had a special guest on hand: Orucase co-founder Isaac Howe. Isaac gave us plenty of detail on the magical folding full-size travel case Orucase has in development, shared with us a bunch of tips on how to pack your bike for a trip, and described how he sees the future of traveling with your bike in general now that most of the US domestic carriers no longer charge oversized fees. TL;DR version: it’s time to go into weight weenie mode.

What were the coolest things we saw at Sea Otter today?
The Sea Otter Classic trade show is back for 2022, and the Nerds are on site with a special episode, recorded right on the expo floor! James, Dave, and Caley talk about the coolest things we saw at the show on day one — like lower-priced 3D-printed saddles and one seriously sweet garage door opener, of all things — and then we chat gravel tire trends with Vittoria’s VP of product development, Ken Avery.

Inside the mind of mad scientist custom builder Rob English
Rob English is one of the most highly coveted builders of high-performance steel bikes these days, and he’s also an elite athlete in his own right. His distinctive function-over-form style is very much rooted in his engineering background, but much of his vision and creativity comes from his eclectic experience in folding bikes, tandems, recumbents, unicycles, and even HPVs. What makes English tick, and where does he get his ideas from? How much skinnier does he think his seatstays can get, and what does he think of the UCI? It’s definitely an entertaining and enlightening conversation that you won’t want to miss.

High-end aluminum bikes and dropper posts for everyone?
Things have been a little wacky in the road bike world lately, with Specialized launching a new Allez Sprint high-end aluminum race bike that’s both heavier and more expensive (but potentially better?) than the one it replaces, dropper seatposts in pro racing, and bikes that positively laugh in the fact of that 6.8 kg UCI weight limit (how about 3.3 kg instead?). Plus, ever wonder what word sets off Zach? Yeah, we were a little surprised, too. Add in another round of Ask a Mechanic, and you’ve got the makings of yet another fantastic episode of Nerd Alert.

Confused about tubeless and tire pressures? You’re not alone.
This week’s Nerd Alert episode came about after consumer-direct wheel company Hunt released a 1,213 g ultralight disc brake road wheel with a hookless tubeless rim. Where some of the other more prominent hookless road wheels have 23 to 25 mm internal widths to supposedly support the tyre at lower pressures, Hunt’s have a marginally narrower 21 mm figure. And with that, some readers raised questions through our Mailbag column over whether the recommended 72.5 psi maximum pressure actually makes sense for riders of average weight and on popular road tyre widths of 25 and 28 millimetres. As a technical consultant to some winning WorldTour teams, Josh Poertner of Silca flicked us a message with some thoughts on the matter that only raised more questions. And that got us thinking, perhaps it was time to check-in again on where we’re at in the world of road tubeless, what’s new, what’s coming down the pipeline, and what still needs to be fixed. Join Dave Rome, James Huang and Josh…

Finding the best chain lube for your needs
This week we’ve got a deep dive episode on a topic that’s applicable to everyone that rides a bike. Chain lube. As we’ve covered plenty before, the difference between running a good chain lube suited to your riding conditions versus a poor lube can come at an enormous financial cost to parts replacements, and that’s if you can find the parts to begin with. Unfortunately, there’s no doubt a load of BS floating around when it comes to chain lubes and what’s best. In August 2021 we had independent chain lube tester, Adam Kerin of Zero Friction Cycling, on the podcast to dive into the murky world of chain lube testing and why many claims just don’t stack up. This time Adam joins the pod again with a practical list of useful take-aways that your drivetrain will love and a few popular myth busters.

LeMond is back in the road business, but is it for real?
We’re back with another group show this week, and taking a hard look at the new LeMond 8 carbon aero road bike that was announced last week. It sounds sweet, and includes a lot of intriguing features like structural foam filling, internal carbon truss reinforcements, size-specific chainstays, and — get this — carbon threads in the bottom bracket, bottle mounts, and derailleur hanger. There’s so much we want to love about the thing, but also a whole bunch of red flags. We also discuss the pros and cons of Wahoo’s new Kickr Rollr smart trainer, imagine a world with wireless e-bike chargers, and then finish off with a whole bunch of reader questions in our Ask a Mechanic segment.

Custom options are great, but only if you’ve got the parts on hand
Lots of things have been hard to come by over the last year or two, and while it’s definitely been a big inconvenience for a lot of us, it’s potentially crippling if you’re trying to sell bikes — and maybe especially so if you’re a consumer-direct brand like Fezzari that has a full range of bike types and also prides itself on offering a huge list of custom options. Ever wonder what the logistics look like for such an operation? It’s as complicated as you might think, but thankfully, it turns out some people actually enjoy figuring that stuff out.

OldGrumpyH8ters gonna hate
Roval and Specialized appear to be returning to road tubeless after last year’s curious non-tubeless tubeless wheel launch, we question the merits of Ratio Technology’s latest 12-speed conversion kit, and — no surprise — Shimano made a heck of a lot of money last year. But we also now have more concrete proof that the Covid-fueled bike boom might finally be cooling off a bit. And what’s Dave Rome’s favorite chain checker? What’s on the Nerds’ wish list for internal cable routing? How do you graphics off of DT Swiss hubs? And do Cushcore gravel inserts work with all rims? We tackle all of that in this week’s Ask a Mechanic segment.

Maybe slower is better when it comes to cycling clothing?
Apparel — apparel in general, not just cycling-specific stuff — is predominantly manufactured in bulk, with orders placed through contract factories well before anything will actually be offered for sale. It’s done this way because it’s cheap, but it also carries a lot of downsides, like the uncertainty of forecasting, long lead times, and literal mountains of waste. Maybe there’s a better way? US-based brand Kitsbow certainly thinks so, and while their sewn-on-demand business model has hurdles of its own, there certainly seems to be an awful lot of upsides.

Will all bikes eventually be sold consumer-direct?
Specialized rocked the industry last week with the announcement of its Rider Direct program, which allows buyers in select markets to have complete bikes delivered right to their door — either by a participating dealer or in a cardboard box. Dedicated consumer-direct brands like Canyon and YT bike brands already do this, of course, but Specialized is the first major traditional brand to go that route. Without question, the world has gotten used to buying anything and everything online, so this is clearly where things are going. But is it a good thing or a bad thing for consumers and bike shops? And when might other brands follow suit? We discuss this — and more — in this week’s episode.

How do you know you’re not buying a used bike lemon?
Former MTB pro Nick Martin started The Pro’s Closet out of the back of his old VW van 16 years ago, and now it’s a multi-million dollar operation with nearly 200 employees, a monstrous warehouse, and roughly 2000 used bikes for sale on any given day. TPC’s ace-in-the-hole is its Certified Pro-Owned program, which promises you’re getting a used bike that’s been fully inspected, serviced, safe, and ready to go — and it even comes with a 30-day return policy. The CPO thing has worked wonders for the used car industry, but does this it sense for used bikes? In this uncertain world we’re living in these days, maybe a little certainty is what we need.

Lights, camera… action?
The Nerds had quite a few new bikes to talk about this week, and a lot of details to debate, especially regarding Cannondale’s new Synapse. On the one hand, it’s strikingly normal now with no proprietary fittings whatsoever (even a threaded bottom bracket — from Cannondale!). But there’s now also a fully integrated onboard battery powering built-in lights and a custom rear-facing Garmin Varia radar. Is this a good thing, or is it a little half-baked? Meanwhile, Canyon has moved away from threaded to PF86 for its latest Endurace range, which seems nuts at first… but is it, or is there more nuance to it? We also discuss SRAM buying computer brand Hammerhead, the same end for Bowman Cycles, and we hammer through a small army of Ask a Mechanic questions. Don’t miss it!

Gravel tech Q&A with Geoff Kabush
It turns out Canadian pro Geoff Kabush is pretty good at racing bikes — first in XC MTB and cyclocross, then more recently, gravel and enduro — and throughout it all, he’s never been afraid to speak his mind. But along with chasing podiums, Kabush has always also put his engineering degree and technical mindset to good use in a product development role, providing valuable feedback on what works, and what doesn’t. So what’s he think about gravel gear? James and Dave ask the questions, and Kabush provides the answers.

Is adjustable geometry a genuine feature or just another gimmick?
The Nerds are finally back with another group show! This week, one of the things we’re discussing is one of the hottest trends in gravel bikes: adjustable frame geometry. On paper, the idea of having multiple bike personalities in one sounds awfully appealing, but how much of a difference does it really make, and how many people are actually going to use it regularly? Is it a way to really make bikes better, or is it just a way bike brands can hedge their bets? And what happens if it’s done poorly? As always, we have opinions.

The ins and outs of 3D-printed saddles
3D printing is the hottest new development in manufacturing, and as far as cycling goes, saddles have curiously emerged as an area that has seen the most widespread application with several models on offer from both Fizik and Specialized (and more to come, surely). Although they’re horribly expensive, 3D-printed saddles have also proven to be freakishly comfortable while still being extraordinarily light and highly supportive. But what makes them so comfortable? When might they become more affordable? And why do they have to look so weird? In this week’s episode, James sat down with folks from Fizik and Carbon — the 3D-printing development partner for both Fizik and Specialized — to get the nitty-gritty details on what 3D-printed saddles are all about, and where they’re heading from here.

Designing a cyclocross race bike that isn’t a gravel bike
This/next week’s episode of the Nerd Alert Podcast has dropped a little early. That’s because it’s a timely chat about the new Cervelo R5-CX cyclocross race bike that was just announced. Our guests for this episode are Cervelo’s director of product management, Maria Benson, and the company’s engineering manager, Scott Roy. Dave Rome fills in as host and chats about all the nerdy details of the new model (such as the new threaded bottom bracket!) that was designed specifically for Marianne Vos and Wout van Aert. It’s worth a quick note to say that while the regular CyclingTips podcast does occasionally do special sponsored episodes that take a deep dive on new bike releases, this isn’t one of those. Rather we just thought it would be interesting to have a candid chat about the discipline-specific design elements that some of the world’s best racers request.

However, a new indoor bike called Tiltbike from UK outfit Muoverti nevertheless gives us some hope that we’ll see something like that from someone because built into one of its levers is — for real — a joystick!

All of our bikes and parts should be repairable
The Right to Repair movement primarily targets the electronics industry, but the concepts behind it strike at the heart of cycling, too: Products should be designed to be repairable, all small parts should be made available — and stay available — manuals, tools, service procedures should be accessible to everyone, and it shouldn’t cost more to repair something than it costs to replace it. In fairness, it’s not all that bad in this respect as far as the bike industry is concerned, but it could be better.

It turns out even pro teams can’t get bikes or parts, either
Sorry, folks, we know our usual Nerd Alert schedule has been a little off-kilter, but we figured it’d be better to shuffle things around to accommodate the World Championships — and next week, Paris-Roubaix! Thanks for your patience, and rest assured, there’s more Nerd Alert to come sooner than later! This week’s episode takes The Nerds to the UCI Road World Championships in Belgium! Caley, Ronan, and Shoddy scoured the team pit areas for all the shiny new bits, and they found what looks to be new hookless-compatible GP5000 tubeless tires from Continental and some interesting new rollers from Wahoo Fitness. Worlds is always a weird one for the mechanics given the mix of national and trade teams, and it’s even weirder this time around. We’ve all grown accustomed at this point to not being able to find bikes or parts, but if it makes you feel any better, it turns out that even top pro riders and teams can’t get them, either. A Roubaix win on Shimano 105??? Stranger thing…

3T’s homegrown Italian robots and the future of carbon fiber
3T recently wound down its carbon fiber frame production in Asia and brought it in-house to Italy. Manufacturing frames the same way would have prohibitory expensive with Italian labor costs, though, so 3T instead developed an entirely new, and highly automated, process that not only dramatically slashes the amount of manual labor required, but also supposedly makes the frames better. What’s the secret sauce in 3T’s new frame building technology, and what are the company’s plans for it moving forward? In this episode of the CyclingTips Nerd Alert podcast, we sit down — virtually, of course — with 3T co-owner Gerard Vroomen, who gives us the full scoop on what this technology is, how it’s different, and what its future might look like.

Inside the mind of Dangerholm
This week’s Nerd Alert podcast is a deep dive into the mind of Gustav Gullholm, aka, Dangerholm. Dangerholm is best known for building crazily light and bling mountain bikes, whether they’re for cross country racing, enduro or even downhill. And in recent times some of his builds have included stealthy integrated electronic shifting, or hacked suspension lockouts and dropper posts that run off a single controller. Now the Jort-wearing Swede has turned his attention to the drop bar world and modified his first gravel bike. Senior tech editor Dave Rome chats to Gustav about the new build, the design process of such bikes, and DIY paint. If you haven’t already, then be sure to check out the full feature on Dangerholm’s Scott Addict Gravel.

Separating chain lube testing fact from fiction
Welcome back to the Nerd Alert podcast, in this week’s episode Dave Rome steps in as host and goes full nerd while diving into the murky waters of chain lube testing. The amount of mixed information related to chain lubes is staggering and it’s undoubtedly one of the more confusing product areas for consumers. That’s an issue because your choice of chain lube can make a substantial difference to the durability and efficiency of your drivetrain. To help unravel these issues we called up Adam Kerin of Zero Friction Cycling and the founder of FrictionFacts Jason Smith to talk all things within their domains. Here they reveal what makes a great chain lube, what tests work and why, and what tests you should be sceptical of. For related reading, stick your head down the rabbit hole of all things related to bicycle chains.

Groupsets may be particularly hard to find, but it’s important to remember there are more options than just Shimano, SRAM, and Campagnolo. Are off-brands like Microshift truly diamonds in the rough, or is it yet another example of you-get-what-you-pay-for? The Nerds also chat about how the most recent Strava updates might help prevent bike thefts, an encouraging new way to buy refurbished cycling clothing, and the pros and cons of $30 socks.

The world of carbon fibre composites is continually progressing, and yet, the way most carbon bicycle frames are made today doesn’t differ all that much from how it was done in the 90s. However, aeronautical and automotive industries are continually investing in improved methods and processes, and the cycling market serves to benefit from just that. One such example is the recent rebirth of thermoplastic composites which have the potential to reduce costs, offer superior impact resistance, and be recyclable. Our guest in this week’s deep dive episode is Ben Lloyd, a Research and Development specialist at Cygnet Texkimp Ltd, a leading carbon composite manufacturing machinery company. Lloyd is an expert in thermoplastic manufacturing and also in touch with the bicycle industry.

Just because you can 3D-print it doesn’t mean you should
3D-printing is an undeniably cool way to make things, but that doesn’t mean it’s always the best way. Is a printed titanium hammer better than a welded one? Do $2,000 printed cycling shoes move the bar enough to justify their existence? What’s the point of printing sunglass frames? And was that handlebar that failed so dramatically at the Olympics even 3D-printed at all? What is definitely very neat, however, is a new trend whereby companies like Muc-Off are starting to ship products in powder form whereby you add the water at home, instead of the company burning resources to ship mostly water around the globe. We also chat about Ibis’s move to local frame production, an insane alleged Ponzi scheme involving three well-known Italian cycling brands, and finally, we finish up this week’s episode with a bunch of reader questions for our always-entertaining Ask a Mechanic segment.

Something old, something new, something borrowed, something red, white, and blue
Track events at the Tokyo Olympics are set to kick off next week with a full week of exciting racing around the 250-meter Izu velodrome. Felt is once again the official bike sponsor of the US team, and the company has supplied a brand-new bike — the TK FRD — for mass-start events that features a new aero shape and a new take on the frame geometry. But for the individual events, the American riders are on the same bike as they used in Rio five years ago. In an event where fractions of a second can have major impacts, and when several other federations have brought radically cutting-edge machines to Tokyo, how is it that the Americans are using bikes that are half a decade old? Then again, maybe all isn’t as it seems.

Oversized derailleur pulleys for everybody!
Oversized rear derailleur pulleys might be good for some marginal gains, but even the terrible watts-per-dollar ratio hasn’t stopped a growing number of brands from launching their own versions — and AbsoluteBlack’s HollowCage is now one of the most expensive ones out there (but also one of the blingiest). Speaking of looks, is a clean front end enough to justify all high-end road bikes going to fully internal routing in spite of the adjustability and serviceability headaches? And how much bigger are road tires going to get? We discuss all that and more in this week’s episode.

So you say you want to build your own carbon frame…
It’s not uncommon for custom frame builders to change direction from time to time: from lugged to TIG, steel to titanium, maybe different bike styles. But it’s far more unusual for an established builder who specializes in metal to make the wholesale switch to carbon fibre — and not just tube-to-tube construction, but moulded frames like the major brands. Yet that’s just what Carl Strong has done with his new venture, Pursuit Cycles. What’s involved in starting something from scratch? Why embark on something so challenging? And what would those frames offer to people that you couldn’t get already, anyway? Strap in for this deep-dive episode.

On the roadification of gravel bikes and the return of molded carbon wheels
Gravel bikes were once the rebels of the drop-bar bike world, but now that they’ve gone increasingly mainstream, it’s perhaps inevitable that they’d adopt features from road racing: aero shapes, hidden cabling, similar claims about weight and stiffness, and so on. Is this a good thing? Also making a possible comeback are solid molded carbon fiber wheels — and they’re not just for fixies, kids. And what do we think you should bring with you on an unsupported 4,700 km ride? You’ll get all that and more in this week’s round of Ask a Mechanic.

The scoop on that crazy single-sided Cervelo, and digging for details on Cannondale’s new TT bike
This week’s Nerd Alert episode takes a closer look at two recent events in this year’s Tour de France. In stage 1, Jumbo-Visma rider Steven Kruijswijk finished the stage missing an entire seatstay from his prototype Cervelo, and in stage 5, EF Education-Nippo riders tackled the stage 5 individual time trial on a new Cannondale TT bike. We chat with Cervelo to find out how that bike could have possibly survived — and apparently without Kruijswijk even knowing! — and get some tantalizing tech details from Cannondale on that new bike before its official release. Sorry, folks, this one’s pretty long, but we promise it’ll be worth your time.

Preventing mechanicals with pro wrench Brad Copeland
This week’s CyclingTips Nerd Alert episode is a deep dive into preventing ride or race-ending mechanicals and how to deal with them when things do go wrong. For this episode, tech editor Dave Rome rang up mechanic to the stars, Brad Copeland. As the personal mechanic for former cross country mountain bike world champion Kate Courtney, Brad is incredibly detailed in ensuring his riders are able to consistently get to the finish line. The lessons here are just as applicable to everyday road and gravel riders as they are to those racing mountain bike world cups.

Digging through the tech at Unbound Gravel
It seems everything cycling-related is fetching inordinate amounts of money on the used market these days, and so we figured it was a good time to trade in Caley and Zach for a special guest host: Dan Cavallari, former tech editor for Velonews and now freelancer extraordinaire. Dan covered Unbound Gravel for CyclingTips this year, so it only seemed right for James and Dave to run through all the interesting gravel tech with him. Wondering about tire inserts? Tire sizes and pressure? Handlebar setups? Gearing? We go through it all, and bookend it with the usual round-up of tech news and Ask a Mechanic questions. And don’t worry, Caley and Zach will be back next week — probably. Maybe.

Tubulars aren’t dead yet
We’ve chatted an awful lot lately about how tubeless and tube-type clinchers seem to be slowly replacing tubulars in pro road racing. Even though high-performance clinchers offer a big rolling efficiency advantage (as much as 12 W according to some figures), tubulars are still more popular for all the same reasons as usual: they’re lighter, they’re safer if you get a puncture, they handle impacts better, and they just have a distinctive feel that clinchers still can’t quite match. What if you could have a tubular that offered all of that, and yet was also just as fast as top-end clinchers? What might the landscape look like then? That’s just what Challenge claims to have developed with its latest experimental tubulars, and James gets the scoop from the company’s technical director, Morgan Nicol.

Expensive vs. budget carbon wheels, and why Wahoo should look down, not up
In this week’s episode, The Nerds chat about some cool parts and accessories Dave saw at the recent Handmade Bicycle Show Australia, including some hyper-expensive wheels from Partington that are trying to go head-to-head with Lightweight. Carbon wheels have gotten incredibly good at the opposite end of the price spectrum, and we make the argument that, unless you’re dripping with cash, it’s awfully tough to justify the price premium. Speaking of which, we also chat about Wahoo Fitness’s new Elemnt Bolt GPS cycling computer, which makes us wonder where the company might go from here. A new high-end model sort of makes sense, but a killer budget model even more so.

How much mountain bike is too much when it comes to gravel bike geometry?
In this week’s Nerd Alert episode, tech editor Dave Rome has a chat with Australian custom builder extraordinaire Mark Hester of Prova Cycles. Hester was a very early adopter of MTB-style geometry on gravel bikes, incorporating things like long front centers and shorter stems when most other brands — especially mainstream labels — were still using dimensions mostly borrowed from road racing machines. Yet as with anything bike-related, if a little bit of something is good, lots more of it surely makes it even better, right? Hester has some interesting thoughts on the idea, and you won’t want to miss hearing where he thinks things are going from here.

How 3-D printing is revolutionizing the Australian custom bike industry
Australia’s entire population may only be roughly equivalent to Shanghai, but it has an outsized custom bike industry with astonishing levels of ingenuity and innovation. Tech editor Dave Rome recently visited the Handmade Bicycle Show Australia in Melbourne, where 3-D printing is playing a big part in setting a number of these builders apart from the rest of the world. Also in this week’s show, we chat about upcoming developments in gravel bike suspension, whether CeramicSpeed’s Driven shaft-drive drivetrain really will see the light of day now that the company has an extra million bucks on hand and the likelihood that Ineos-Grenadiers riders might race at the Tour de France on clinchers.

Clinchers and inner tubes at Paris-Roubaix?
Team Deceuninck-QuickStep and Bora-Hansgrohe — together with sponsors Roval and Specialized — have been doing a fair bit of experimenting with their wheels and tires over the past couple of years, gradually moving away from traditional tubulars to tube-type clinchers for time trials and tubeless clinchers for road races. In an unusual move, both teams say they’re now wholly committed to clinchers and latex inner tubes for everything — even possibly (but not likely) Paris-Roubaix. To find out more about the surprising decision, James and Dave have a chat with Roval engineering manager Jeff Meyer, as well as three key players from the Deceuninck-QuickStep team: technical director Ricardo Scheidecker, team scientist and coach Koen Pelgrim, and head mechanic Nicolas Coosemans.

And what’s up with the flexy seatposts on those bikes, anyway? The Nerds share their thoughts on those topics and then look into a Specialized patent for a wacky flexy seatpost design of its own. And is the wait finally over for power meter pedals for Shimano SPD-SL pedal fans? It sure looks that way. Last but not least in this week’s episode, The Nerds bring back the “What Bike Should I Buy?” segment to discuss the ultimate one-bike solution — or if it even exists.

Recent filings with the US Federal Communications Commission reveal that Shimano’s next generation of Dura-Ace Di2 will be at least semi-wireless — and not only that, but SRAM looks to finally be bringing its AXS wireless system down to the Rival level. Both developments are very exciting, but what do they mean for wired drivetrains, and will both companies be able to deliver in the current environment? While drivetrains are trending toward wireless, indoor trainers might be moving in the other direction with hardwired connections for better signal reliability.
