Bottom bracket measurement

Description of the video
Bottom Bracket Standards | Park Tool The taper of your cranks: Because all the load is on one very small area of the cotter pin and the crank land the cotter pin deforms plastically under normal use and so must be replaced regularly. January 2, at 8: On a singlespeed fixie, internal-geared-hub , the important measure is how much the right side of the axle "shows out" not always perfectly symmetric , and how much the crank can "sink" into the tapered square, which may vary from model to model even with the same nominal spindle length, and with how much torque you apply to the bolt when installing. It comprises a standard spindle and bearings in a steel cylinder with a slightly-modified bearing cup at each end. Factoring perfect square trinomials or other types of equations are done differently, but I'll show you a basic example.
