Big Steel bearings with gasket seals to fit Monocrome Bottom Brackets.

These bearings have a smaller internal diameter than the standard 6805 bearings, supporting the crank axle directly and removing the need for plastic sleeves.

The gasket seals have been specifically designed by Shockcraft's engineer to fit the Monocrome Bottom Brackets.

Important: FSA MegaExo cranksets have a slightly larger axle that means they won't fit through these Big Steel bearings.  They will however fit with the 6805 bearings and plastic sleeves as there is enough give to allow the larger axle to be pushed through.

Special 6 Months Guarantee:   All Monocrome^TM bearings carry a special guarantee with a 6 month no questions asked replacement.
