Crank Length

Where do i measure crank length? Is it the whole length of the crank? Is it hole to hole? Is it end of hole to hole or centres or what?

Also what’s a good length for a 24"

center to center

What kind of 24? 150s would be good for learning and MUni, 125s would be OK for learning and good for cruising around. You can go shorter for more speed at the expense of control. Longer is great for slow control but can be awkward to try to go fast with.

Centre to centre…thanks saskatch!
