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.
