CeramicSpeed BSA30 30mm Gravel CX Coated Bottom Bracket (Black)

BSA30 Bottom Bracket Gravel

BSA comes from British Standard Cycle, aka English threading. English threading on road bikes mean a 68mm wide, 34mm inside diameter shell with reverse threading on the drive side. It’s the most common threaded standard employed today. This kit allows you to fit 30mm thru-axle cranks, like those from Rotor, to fit in the tight space of this 34mm spindle.

Unsere Gravel-Tretlager sind mit CeramicSpeed-beschichteten Lagern ausgestattet und mit UFO Long Life Grease für ultimative Haltbarkeit und Schutz in allen Umgebungen versehen.

The cups come with CeramicSpeed Bearings installed, coated bearings and hardened-steel races for longer life and less bearing drag.

Technische Daten

English threading is easy to work with and the drive side cup, thanks to being reverse-threaded, stays in place without any extra effort. The threaded extension is thin, as they need to fit a 30mm spindle inside the cups.

The spindle increases efficiency, as is the CeramicSpeed system.Our CeramicSpeed Coated Bearings reduce drag by over 75% when compared to stock bottom brackets. Down to 0.3-0.4 watts per set. This is the result of hardened-steel races, coated with a unique non-corrosive surface finish and combined with CeramicSpeed Balls that are 100% smoother and 15% harder than the ceramic competition, in addition to lasting longer.
