Direct replacement for Monocrome Big Steel, Enduro, Trek Madone (BB90&95) and Hope bottom brackets.
These bearings can also be fitted to Shimano HT2, Raceface X-Type and some Truvativ bottom brackets (with appropriate seals and/or fitting kit).
Big Steel bearings have a smaller internal diameter than the standard 6805 bearings, supporting the crank axle directly and removing the need for plastic sleeves.
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 MonocromeTM bearings carry a special guarantee with a 6 month no questions asked replacement.
