CeramicSpeed SRAM DUB Road T47/86 Inboard Bottom Bracket
CeramicSpeed SRAM DUB Road T47/86 Inboard Bottom Bracket Item # 1828181
Description
The new SRAM DUB crank standard, built on a 28.99 mm spindle, allows for a more contamination resistant BB design, while retaining the ultra-efficient & long-lasting qualities CeramicSpeed Bottom Brackets are known for.
The T47 threaded bottom bracket shell utilizes an oversized interface of PF30 and EVO386, but with the benefit and peace of mind of a threaded interface. T47/86 places the bearings within the width of the frame and is compatible with 85.5 mm wide Trek frames, as well as standard 86 mm wide T47 Inboard frame designs.
With an integrated dust cover for all models, a snug & secure fit that also fully protects the face of the bearing delivers exceptional performance without any sacrifices. CeramicSpeed hand-built bearings carry the load from crank to frame with un-paralleled durability & efficiency.
