Convert your BB30 frame set into the ultimate single speed bicycle. This adapter was originally developed for singlespeed cyclocross racing. However, this adapter will work on any frame that utilizes the BB30 Bottom Bracket Shell Standard. (42mm Inner Diameter)

Cross bikes and road bikes can use any crank with a 24mm spindle. Shimano Hollow Tech II and FSA cranks will work just fine. If you have a SRAM crank, the Chris King PBB009 spacer kit is necessary for the step on the non drive side.

MTB setups should use a mountain crank with a 24mm diameter spindle. MTB cranks are designed for a 73mm wide bb shell so, any MTB crank will need the Problem Solver BB30 spacer kit. You might be able to use a Road Compact Double , but that will require some measuring on your part.

All adapter kits are machined locally in the USA. Each kit includes Phil Wood Bearings , Phil Wood Dust Caps, FSA Friction Paste, and Stainless M5 Bolts.
