Big Steel bearings to fit Shimano HT2 & Raceface X-Type bottom brackets.
The bearings in this kit are bigger than stock, replacing the factory plastic sleeve to support the axle directly on the bearing. Shields are included to protect the bearings from direct contaminant entry.
Silicone Spacer Shield Size: The shields are available in two different sizes. Bottom bracket cups from Shimano require either 37 mm or 41 mm diameter shields. Raceface bottom bracket cups require 41 mm diameter shields. Please select the size you require above.
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.
