What if the cleat is worn out? My LOOKs can't wait to jump out of the pedal when they get worn down
I coach new riders at our track so I see hundreds of mountain bikers and triathletes and am quite used to seeing MTB pedals/cleats. They work for newbies, not sure I've seen anyone race in them, and I would think the bigger issue would be finding a decent shoe that wasn't soft/velcro, and the very small contact point (mixed with a flexible sole).
so it works sure, just as a track bike with very small drop outs, but why make your life harder than it needs to be.
