Welcome ! Your find bicycle crank diagram
Bicycle cranks: rebuke your Cranks! Bicycle cranks: put a damper upon your Cranks! I've been cycling entirely my life, riding to my friends' houses at the time I was a kid, doing 20-odd mile rides viewed like a teenager, and exactly kept going from there. From the leisure I was a teenager to the place I was in my 30's I had merely perpetually used measure amplification (170mm) cranks. soon afterward I bought a mean racer, which happened to take rise immediately after 165mm cranks.}
