CeramicSpeed Bottom Bracket, which converts BB30 MTB frames to fit a standard 24 mm axle like SRAM GXP. Suitable to fit frames with a 42 mm shell inner diameter.

The upgrade is available as a press fit bottom bracket with red or black cups, with standard or coated CeramicSpeed Bearings.

The CeramicSpeed BB30 SRAM GXP MTB are assembled by hand in Denmark and fitted with precision in aluminium cups.

To ensure you the best riding experience when going off-road, this bottom bracket acts as a stiff and efficient system. Every BB30 SRAM GXP MTB is delivered with the special LongLife grease, which makes sure that all properties are secured even when riding off-road. For the MTB discipline, we recommend choosing the bottom brackets fitted with coated bearings, thanks to their high resistance to the damaging effect of corrosive factors and further reduced friction.

The special design of the threaded bottom bracket, where the cups are threaded and screwed together inside the frame, ensure that you avoid any creaking sounds and there is no need for any adaptors.
