The Wheels Manufacturing PF30 Outboard Bottom Bracket delivers rock-solid performance for your frame.
Two precision-machined aluminum cups thread together to lock the bottom bracket firmly in place, eliminating creaks and ensuring smooth, reliable operation. Engineered specifically for 24mm spindle cranks (Shimano and compatible brands) in PF30 46mm ID bottom bracket shells—no adapters needed. The outboard bearing design extends bearing life significantly while making maintenance straightforward. When it's time for service, bearing replacement takes just minutes. ABEC-3 bearings provide dependable smoothness for trail and road riding. Built tough for all-terrain cycling, this bottom bracket combines simplicity with durability.
