Big Ceramic Hybrid 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 available to protect the bearings from direct contaminant entry.
Silicone Spacer Shield Size: These 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.
Ceramic hybrid bearings have a conventional steel outer race but with ceramic balls inside. The harder ceramic balls roll a little easier, weigh a little less and the bearings have been designed to minimise rolling friction. These are ideal bearings for those seeking higher performance and lighter weight.
Important: FSA MegaExo cranksets have a slightly larger axle that means they won't fit through these Big Ceramic Hybrid 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.
