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
