T47 External Bottom Brackets are here! Engineered to balance best-in-class sealing with low drag for superior performance in all conditions. Our ground-up design features custom bearings, seals, bushings, and cups, allowing us complete freedom to dial in each and every detail. Exhaustively tested over years of riding with no off-the-shelf parts. T47e BBs join BSA and T47i to expand our family of Color Shop coordinated bottom brackets.
