Ask Josh Anything #15
Nobody enjoyed seeing (or hearing about) Chloé Dygert's recent crash, but it was an extraordinary illustration of one of the effects discussed in our most recent episode on Bifurcation. Josh breaks it down (and we all wish her a fast recovery and speedy return to racing).
We also discuss UCI frame rules modifications, and how those open the door for changes (some massive, some marginal) in how bikes perform and look.
And of course we take on a slew of awesome listener questions, including:
- Could Primož Roglič have won the Tour de France if he'd paid more attention to marginal gains?
- How to accommodate non-bifurcation segments in a race as well as the moment of bifurcation
- When is Silca going to come out with a pre-treated chain?
- Robert Chung's maxim on bicycles

Question for Josh – Let’s say you have a traditional, round-tubed, steel-framed bike that you love and enjoy and have no intention of parting with but…you wouldn’t mind a little free speed. You could, of course, get more aero wheels, more aero clothes, a more aero helmet, tape your cables together so that they “stack up”, etc. but is there anything you could do with the frame itself that would add aero benefits? I am willing to listen to any and all suggestions except for a big plastic fairing. I just couldn’t.
Having survived a couple of high speed wobble episodes/pucker-fests I always wondered about the following solution. Assuming you are on a straight section of road, would bunny-hopping the bike or lifting the front wheel off the pavement momentarily be a reasonable way to stop the oscillation? This has occurred to me mid-wobble, but usually I just continue hanging on for dear life.
Thank you for picking that up as the caller seemed to think that Pogacar was in a team issued skinsuit as opposed to the tour issued suits.
Question for next Ask Josh Anything: I recall hearing your explanation that spokes passing between fork blades creates disadvantageous high-pressure areas. So why don’t we have a lefty road fork? Are you aware of a one-sided road fork ever having been tested? Have you ever hear aero numbers for a regular Canondale Lefty fork?
I was thinking the same thing while listening. I suspect that the TdF issued suit is roulette with regards to whether the suit is fast on the wearer. At least with their normal team suit you’d expect a very optimised garment for each rider. We could have an entire podcast just on Pog vs Rog in that TT!
