Update: Video here on Instagram, which also shows cyclist Michael Guerra slowing his brakeless track bike by rubbing both shoes against the rear wheel before clipping back in.
This GIF of a guy pulling a superman while rolling downhill on a track bike is making the rounds on various social media.
I think I counted 140 RPM when he releases his feet from the pedals. After watching this animation a buddy reminded me of our lunch rides in Boulder County, Colorado. I’d show up on my fixed gear, and naturally everyone else picked that day for hill work. I’d unclip on fast downhills because my feet couldn’t keep up. On my 42×14 gearing, I’d hit about 200 RPM at 50 MPH. Unlike the guy in the video, I stayed seated and rested my feet inside the front triangle. Also unlike the guy in the video, I rode with brakes.
I’m very good at clipping in, because I had to learn to do it with pedals on the move at about 80 RPM.
