Product Description
The Wheels Manufacturing PF41 ABEC-3 Fat Bike Bottom Bracket is a thread-together bottom bracket designed for fat bike frames using a 41mm shell ID and 121mm shell width. It is made for 24/22mm SRAM/Truvativ GXP crank spindles and fits BB121 and BB132 frame interfaces. The thread-together design helps create a more secure fit in the frame, while ABEC-3 angular contact sealed bearings are well suited to handling combined radial and axial loads. Built with replaceable Enduro bearings and made in the USA, this is a solid option for fat bike drivetrain service and upgrades.
