Convert your BB30 frame to a single-speed setup with our simple to use 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.
- Our Eccentric bottom brackets for BB30 frames will not work with frames that do not have removable c-clips in the shell. If your frame has a shell with a molded step that the bearings press up against, our EBB will not completely fit in to the shell.
