Welcome to Part 2 of our conversation with Joshua Poertner.
The Silca Velo CEO continues to offer his insight into marginal gains, those little performance improvements that can be made when everything that goes into riding a bike is considered. Episode 29 then pivots to pro cyclist Victor Campanaerts’ new UCI Hour Record, 3D-printed helmets, and heat loss through your wrists! We also get into Kev’s favorite gear—the granny gear—and why you might use it.
