Crank length questions

[531Man]

Some people do notice the shorter cranks, others don't.
Some don't even notice odd length cranks, but that baffles me.

A thought here - Not all people have equal inside leg measurements ( nor hand or feet sizes or arm length), so it's quite possible that for some people, different L and R crank lengths are a necessity.
Anyone on here finding this or know of it? Especially if it is amongst the professionals.
Have a Happy New year.

Uneven leg length (unless it's absolutely massive, several cm, something like a serious injury) is usually adjusted by shimming cleats or changing cleat setback (or a combination of both), depending on where the change is.
