Convert your PF30 frame to a single-speed setup with a Wheels Manufacturing eccentric bottom bracket. Enduro Angular Contact sealed bearings. Double lip seals on all bearings with high fill rate top quality grease for maximum durability. Machined aluminum cups are superior in function and durability to plastic. Fully serviceable.
Do not install bottom bracket with the two bolts positioned above the bearing. Some carbon frames do not have proper internal support for the bolts to properly tighten to spec. As a result, the cups will not stay tight in the frame, and at worst, your frame may crack.

- Specialized Carbon OSBB (with additional 3.5mm BB cup spacers -PF3.5-SPC)
Compatible with the following cranksets:
