CeramicSpeed BB30 Shimano MTB 24mm Spindle sport factory

BB30 central shells on mountain bikes call for a special threaded bottom bracket when installing Shimano cranks. Our Bottom Bracket threads into itself and holds the bearings outside the bottom bracket to work with Shimano.

Our shells come with CeramicSpeed Bearings installed. Standard Bearings and Coated Bearings are available. Both feature our low-drag CeramicSpeed Balls. Both have hardened-steel races. The Coated has a coating on the races for less drag and greater durability.

Our CeramicSpeed Bearings start with our CeramicSpeed Balls. They’re 100% smoother and harder than the ceramic competition. Thanks to them installed in our hardened-steel races, our Standard Bearings last three times longer than other bearings. They also reduce drag by an average of 75% over standard bottom brackets. Standard Bearings see frictional drag of 0.3-0.4 watts per set.

The Coated Bearings see a 50% drag reduction and an improvement in bearing life of 60%; another big bump in performance.

24mm thru-axle spindles are compatible with this bottom bracket.

Performance can be improved by changing the grease. LongLife Grease comes installed, but can be changed for lower drag All Round Grease for lower drag or less messy conditions.
