I ride 172.5 cranks on my road and gravel bikes, and 175 on the mtb. Thinking about a basic 8 speed group for a trainer bike, but the cranks only come in 170 and 175.
I was thinking of going down to 170 for slightly better spinning/cadence, since I don't really need the leverage of a longer crank inside. Any other thoughts (besides it doesn't matter)?
