72 - Look Cycle Product Manager Pierre Facomprez

Endurance Innovation is now on Patreon! Have a peek at our page and show us some love.

• 2:00 meet Pierre Facomprez, product manager at Look Cycle
• 6:00 a fun digression about swapping the drivetrain to the left side of the bike for track racing
• 14:00 the aerodynamic benefits of solid-spoke (tri-spoke) wheels
  • This is a debate on the front wheel only. In the rear, use a disk whenever permitted
  • Rotational drag is 25% of the total drag generated by the wheel (source DT Swiss)
  • Disk brakes mean more spokes, which increases rotational drag. Solid spokes do not contribute to rotational drag when mounted on modern, wide forks. 
  • Modern tri-spoke wheels are using less-deep spokes that taper towards the rim
  • Weight penalty for a disk brake tri-spoke vs a similar depth traditional spoke wheel is about 200g (tri spoke is heavier)
• 37:15 Pierre’s hidden valve trick
• 43:00 tri suits
  • Make sure that the pad works!
  • Test your suits. The difference may be substantial 
  • Try your suit on the bike when it’s wet and de-wrinkle after the swim
  • Calf sleeves can be quite fast 
• 58:00 the Aergo cockpit. Comfort equals speed.
