The Bikone DCTech T47 Internal Bottom Bracket - Steel Bearings - SRAM DUB is designed for demanding cyclists looking for performance and durability, whether on technical mountain trails or on the road.

Thanks to Dual Cup Technology (DC Tech) and high-quality bearings, this bottom bracket guarantees exceptional pedaling fluidity.

For Sram Dub Wide cranksets, the purchase of a Dub Wide adapter is required.

For optimal compatibility, mountain bike cranksets should always be mounted on mountain bike frames, and road cranksets on road frames.
