CeramicSpeed BB386EVO SRAM DUB bottom bracket - for 28.99 mm axles

The CeramicSpeed BB386EVO SRAM DUB bottom bracket is used to mount a SRAM DUB crankset with 28.99 mm axle diameter into a 386EVO frame. These are characterised by bottom brackets with 46 mm shell diameters and 86.5 mm shell widths. The bottom bracket comes with ceramic bearings, whose smoothness and load capacity are far above average. This ensures reliable and efficient power transmission from the crank to the bike.

Technology:

Ceramic Bearings by CeramicSpeed
CeramicSpeed ceramic balls are rounder, harder, smoother, lighter and more resilient than steel balls and ceramic balls from other manufacturers. CeramicSpeed ceramic bearings therefore last 3 to 5 times longer than other commercially available bearings. All CeramicSpeed bearings are manufactured by hand in Denmark under clean room conditions and are subject to a strict four-stage control procedure. Among other things, the size of the ceramic balls is checked down to the thousandth of a millimetre. Tests are then carried out in the laboratory or preferably by professionals in training and competition. CeramicSpeed bottom brackets guarantee you the lowest possible friction, optimised power transfer and maximum durability and also help you save watts and reach the finish line faster. It's not about seconds, it's about minutes!
