Cervelo debuts new aero and climbing bikes at the Tour de France that couldn't be more different, yet also match in one very important way, and we've also spotted the Visma–Lease a Bike squad rolling on prototype Reserve wheels laced with carbon fiber spokes.

Tadej and the rest of the UAE team won't feel left out, though, as they're using the just-released ENVE SES 4.5 Pro wheels. But what about that kinda-hook bead rim? Alvin Holbrook and Mike Levy delve into the details as they discuss tire retention and UCI-mandated width regulations that likely played a role in the new rim design.

They also agree to disagree on Mathieu van der Poel's newest sponsor signing with a private jet company that has many fans up in arms, and Levy talks about his first bikepack race adventure at the BC Epic 1000 that included all the heat, not enough calories, and plenty of time spent laying on the ground.
