These bottom brackets are equipped with hand built coated bearings specially developed for off-road performance that offer extreme durability and feature a unique design for SRAM DUB 28.99 cranks.

Coated bearings utilise the highest quality CeramicSpeed ceramic balls, running on hardened-steel races with a 3-micron thick metallic coating making the races corrosion resistant, harder and smoother, increasing service life and reducing friction.

This product has a unique design specifically for SRAM DUB 28.99 cranks. With native fit frame interface and no plastic adapters or excess spacers. This design features a custom integrated dustcover for maximum durability. 

The maintenance of your CeramicSpeed Bottom Bracket is very important. As a general rule, when riding off-road, we recommend servicing your bottom bracket after 1-3.000 km or at least once every year.
