AJA #52: Protocol Tire Tech-Cargo Bibs-Long Sleeves for Aero

Hottie and Fatty pepper Josh with tire questions. Specifically what is and is not a radial casing and how his team was able to move towards a radial ply angle without disrupting tire stability. Josh also explains how they arrived at Protocol's knob shapes and patterns.  From our listeners we have quesions on putting gels in cargo bibs. Does this result in unecessary heavy lifting? Josh answers one on the optimal place to mount a mini pump. On the downtube or the seatube? We also get into why in the spirit of manipulating air flow we don't see more pros wearing long sleeve jerseys?
