Is lower slower? Aero part 2 with JP Ballard

Part 2 of our listen back to when JP Ballard of SwissSide joined us for part one of our Performance Process deep dive into all things aerodynamics.

Ballard is founder and CEO of aerodynamics specialists Swiss Side. The Swiss company produces wheels and aero calf sleeves, but the majority of its work is in offering its aerodynamic expertise to other manufacturers in the cycling industry. He had also sat down with us in January 2024 to record three hours worth of discussion and advice on aerodynamics and performance.

In part 2 we discuss if lower and narrower is slower or faster, acid tests for assessing aero marketing, and why aero matters regardless of what speed we ride at, even uphill.
 
We then delve into where’s best to spend your money chasing aero gains, the best bang for the buck, so to speak. Finally, perhaps the biggest takeaway is that JP doesn’t believe the rule of 105 is as critical as we once thought
