Brand New C-Bear Ceramic Road Bottom Bracket, BSA threaded for 24mm axles such as Shimano, Rotor3D and Race Face
(68-73mm bottom bracket width)

C-Bear Ceramic Bottom Brackets have gained a reputation for being some of the best on the market. I bought this earlier this year as a spare, but have ended up changing cranks to SRAM DUB and had to buy new BB to fit them. So this spare no longer required.
