rear end question

The distance from the bearing to axle face is different on SBP and LBP. Distance is longer on LBP and the brakes do not transfer across.

Cass has proper length axles so you don't have to monkey with the blocks/buttons. Most of the axles out there are not the proper length, too long. If you shoose to go BBP, Tell Cass what you have, style of Sure Grip, and he'll get you set up with what you need for axles.
