Tubulars aren’t dead yet Jun 04, 2021

Show notes

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 May 27, 2021

Show notes

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? May 21, 2021

Show notes

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 May 14, 2021

Show notes

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... May 07, 2021

Show notes

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 Apr 30, 2021

Show notes

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? Apr 23, 2021

Show notes

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.”

The science of Everesting Apr 16, 2021

Show notes

This week Caley and Ronan interrupt the regular schedule to bring you another deep dive episode. Deep diving into the science of Everesting, the Nerds discuss the training, wattages, equipment selection, marginal gains, and time left on the table from Ronan’s recent Everesting world record ride.

Can computers make us faster cyclists? Apr 08, 2021

Show notes

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.

What worked — and what didn’t — on Ronan’s crazy-light Everesting bike Apr 04, 2021

Show notes

Ronan Mc Laughlin joins us this week to go over the details of the hyper-optimized bike he used to shatter the Everesting record. 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. Finally, does it make sense to build your own bike from scratch using open-mold frames and parts since new bikes are nowhere to be found?
