No idea how to quote on this, so this will have to do…
I never really understood everyone’s insistence on running the thinnest pedals possible (at the expense of a decent concave, good sized axles, bushings and bearings) and then mount them to long 175mm cranks. You could have a more robust pair of pedals and just fun 165mm cranks for clearance instead.
These look nice but rather pricey.
Pedal depth is more for pedal stability, at least for me. The closer your foot is to the axle the better in my experience, mainly on rockier/chunkier trails. You can still get pedals with concave with a narrower centre, it’s just that most brands don’t seem to really care about putting much concave at all in pedals these days for some reason.
