Description

Details

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.

Additional Information
Bearing Press Service:

These bearing kits are available with or without Shockcraft's bearing press service.  By having us press the bearings into your existing BB cups, remove the risk of bearing damage during installation.

If you'd like us to press the bearings into your bottom bracket for you, simply also purchase the Bottom Bracket Bearing Press Service.  You will receive an order confirmation email with details on where to send your bottom bracket for its service.  Turn around time is 2 to 3 days.

CNC Storm Drains:

For those riding in wet conditions we can CNC water drains into your bottom bracket cups during bearing replacement.  These water drains allow water to escape from the cup before it can corrode or enter the bearing.  The modification is invisible once the bottom bracket cups are assembled.
