CeramicSpeed BB30 SRAM DUB Road Bottom Bracket, 42 x 68 mm

BB30 SRAM DUB Road bottom bracket by CeramicSpeed - reliable power transmission

The CeramicSpeed BB30 SRAM DUB bottom bracket is compatible with SRAM DUB cranks (28.99 mm axle diameter). It enables their installation in a BB30 Road bike frame with 68 mm wide bottom bracket and 42 mm shell diameter. Ceramic bearings are used here, which are characterised by their particular suppleness and load capacity. In this way, the bottom bracket ensures reliable and efficient power transmission from the crank to the bike. Choose between black or red bearing cups.

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!
