Risks vs. rewards of internal cable routing
After several weeks on the road, the Nerds are finally back in the studio! We’ve got a lot to talk about this week, too, like why the same kinds of fork recalls seem to be happening over and over again, what Pon’s recent takeover of Dorel Sports means for consumers and retail, and a recap of the cool stuff James saw at the recent Sea Otter Classic in Monterey, California. We also start digging through the giant pile of Ask a Mechanic questions we’ve accumulated, like if you can run road tubeless tires without sealant, what chain lube to use if you’re lazy, and whether you should grease your freehub body before installing a cassette. Make sure to have some popcorn handy!

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 things have happened.

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.

Clearing up the confusion about road tubeless wheels and tires
Are you confused about road tubeless? What works and what doesn’t? Is there an actual rim standard yet? What’s the deal with hookless rims? And why is the whole situation with road tubeless such a mess, anyway? Helping us answer all of these questions — and more — is Zipp product manager Bastien Donzé, who may be feeling a little sore after the flurry of questions the Nerds sent his way on this week’s show.

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.

Desperate times call for desperate measures
We all know there’s still a massive worldwide parts shortage going on. Need a chain? Cassette? A suspension fork??? Ha ha, good luck with that. 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. Last — but certainly not least! — we reveal the banging new jingle for our Ask a Mechanic segment.

Thermoplastic carbon composites are back!
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.

Wireless 12-speed Shimano Dura-Ace is real!
The full crew is finally reunited for this week’s Nerd Alert podcast! Now that Shimano’s new 12-speed Dura-Ace Di2 groupset has made an appearance in the wild, we dive into what we can confirm (it’s black), what we think (wiredless?), and what we hope to see (a mechanical version in polished silver!!) in the company’s new flagship road components. We then debate the pros and cons of hookless road wheels, the idea of a flat-proof tube, and finish with an extended Ask a Mechanic segment with questions fielded exclusively from our Veloclub members — and Zach mostly kept his promise to not be too salty this time around.

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.

Summer is coming, but don't put your trainer away yet...
Indoor training is not top of the list of things most of us look forward to in the summer, but should it be? When the summer sun consistently comes out, the turbo trainers usually go into hibernation. We investigate if maintaining some level of indoor milage might improve your fitness and if World Tour pros are moving indoors for sessions regardless of the weather. Ronan chats with David Bailey (head of performance at Bahrain Victorious), Stephen Barrett (coach and head of research and innovation at AG2R Citroen), and Jonathan Lee (TrainerRoad) about indoor training gains and losses.

High fashion meets high tech: the science of cycling clothing
Cycling apparel may look similar between various brands, but when you dig a little deeper, there are often seemingly small variations that can make a world of difference in terms of how well they work out on the road. In other words, that tag may say “polyester” on it, but that only tells one tiny part of the story — and it’s time to learn a little more about the rest of it.

Electronic shifting is supposedly what people want — but is it what they should want?
The Nerds have an awful lot of tech news to talk about this week, such as SRAM’s recent decision to seemingly go all-in on electronic shifting, the ins and outs of two big high-end wheel introductions, the unmentioned pitfalls of fully internal cable routing for everyday enthusiasts, and some big changes for DT Swiss’s workhorse hubs. There’s also been yet another push in the drivetrain friction front from Silca that uses... diamonds? Finally, we debate the ideal gravel bike in a What Bike Should I Buy segment for a new gravel rider on a “flexible budget.”

TrainerRoad offers training plans and workouts for the individual rider and has always been focused on making us faster. They recently launched an Adaptive Training method that combines machine learning and science-based coaching to adjust training plans based on coaches feedback. The goal? "So you get the right workout, every time". This week Ronan chats with TrainerRoad co-founder and CEO Nate Pearson about the new Adaptive Training and explains just how it knows what it's doing. They also discuss what the future might hold and if Adaptive Training can replace coaching as we know it.

Ronan Mc Laughlin joins us this week to go over the details of the hyper-optimized bike he used to shatter the Everesting record. Weight matters a lot here as you’d expect, but so does aerodynamics. Canyon’s precious container of new bikes is finally free from the grips of the Suez Canal, Enve announced its new custom carbon fiber road bike program, we question if we’re all worrying a little too much about weight (and paying the price as a result), and we finish up with a discussion of whether it makes sense to build your own bike from scratch using open-mold frames and parts since new bikes are nowhere to be found.

Designing bikes when there’s no stock
You’ve heard us talking about the supply issues currently facing the booming cycling industry, so this week we dive into what it’s like designing bikes when things are in such short supply. Our guest this week is Sydney-based materials engineer and bike designer Dave Musgrove, someone who’s deep in the industry and in touch with the industry’s Covid-related supply issues. From two year lead-times on certain components to slower and more expensive shipping, this conversation details why you may want to hold onto your existing bike for a little longer. Dave Musgrove is the brand manager for Polygon Bikes in North America and Oceania, a consumer-direct bicycle manufacturer sold through bikesonline.com.

MIPS, new Speedplay, and our sketchiest repairs
James, Dave, Caley, and Zach discuss a wide range of topics in this week’s episode, like how much Speedplay’s revamped pedal lineup matters relative to the changes to its dealer service, whether MIPS really is a must-have when it comes to helmets given lingering questions over human scalps and hair, and what drastic changes in Cervelo’s sales figures indicate about changes in the drop-bar bike market. And then in this week’s Ask a Mechanic segment, we tackle perhaps the most important repair and maintenance question of all: what’s the sketchiest repair job Caley has ever done?

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.

Broken handlebars, flexy seatposts, and power meter pedals to the (Shimano) people
Mathieu van der Poel didn’t let a little broken handlebar on his Canyon Aeroad keep him from finishing Le Samyn, a cobbled race in Belgium, but why did it break? 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.

Can cycling apparel brands cut back on plastic bag use?
With very few exceptions, every piece of cycling clothing you buy comes in its own individual bag — or “polybag” as it’s commonly called in the industry. When you take into account the size of the global cycling apparel industry, and the number of individual garments, that’s a lot of plastic bags. Has it always been this way? How did we get here? And what do we do about it? In this week’s episode, James chats with two apparel brands, Ornot and Pearl Izumi, to assess the current state of things, find out how things are already improving, and why we still have a long way to go.

Are custom wheels really better than factory-built ones? How would you build a set of wheels for a light rider versus a heavier one? What are some strategies you can pursue at home if you want to get into the basics of truing, or maybe want to build a set of wheels for the first time yourself? Hope you’ve got some time set aside because we get real nerdy on this one.

Wireless for everybody!
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. Finally, we tackle a whole bunch of fresh questions in our Ask a Mechanic segment (and Caley actually has something meaningful to contribute this time around).

You might look at tools just as utilitarian items — cold lumps of lifeless steel. For the true believers, the difference between good tools and bad ones is like the difference between gas station sushi and the real thing: they both might get the job done, but one is certainly a lot more satisfying, while the other is more likely to leave you feeling more than a little bit of regret. But, what makes a good tool, why is designing one so hard to do, and why should you care? James and Dave get the lowdown with Jason Quade from Abbey Bike Tools.

We discuss the lawsuit filed against Trek and Bontrager for their allegedly outlandish claims regarding WaveCel helmet technology efficacy, the way ZwiftHub is out-Zwifting Zwift in a few key ways, and the pros and cons of Sea Otter’s recent announcement that they’re moving the show (at least for 2021) all the way back to October instead of April. Finally, in our Ask a Mechanic segment, Caley and Zach reaffirm their disapproval of chain waxing (Dave and James are still fans), we provide some ideas on how to keep your bike from corroding into nothingness in harsh winter conditions, and debate the wisdom of drilling holes in your frame and fork (spoiler: it’s a bad idea).

The fifth element - magnesium stages a comeback
We’ve said before that we’re in a “golden age” of chain lube these days, with big advancements in recent months that not only reduce drivetrain friction but dramatically extend the lifespan of your components, too. We discuss the latest releases from CeramicSpeed and Silca — one for wet conditions, the other for dry — and make the argument for why they’re actually better bargains than you might think. We’re also on the cusp of a potentially big revolution in frame materials, with magnesium finally emerging (after multiple attempts in the past) as a truly viable alternative to carbon fiber, aluminum, titanium, and steel. James chats with Bruno Maier, the president of “Super Magnesium” maker Allite Inc., to find out exactly why magnesium is so promising, and why this time around might be different than before.

It doesn’t have anything to do with the bikes themselves, though; it would apply to bottles and cages. Existing rules for aero tube shapes are also about to change either way and how exactly that will affect the shape of future bikes is anything but certain.

Does bike weight really matter?
Ok, show of hands: who among you has picked up a bike to see how much it weighed? That’s what we thought. Here’s the thing, though: Although we all know that it’s easier to climb on a bike that’s lighter than one that’s heavier, what isn’t as obvious is exactly how much it matters. And as it turns out, it doesn’t matter as much as you probably think it does. In this episode of Nerd Alert, tech editor Dave Rome takes a deep dive into the hard science of how mass affects performance in relation to other factors like aerodynamic efficiency and friction. How much is too much? How do we know when a certain amount of weight savings will really help, and by how much? How much should we care about any of this, anyway?Fair warning: If you’ve always considered yourself a weight weenie, be prepared, because you might not love what you’re about to hear.
