Shimano Ultegra SM-BBR60 Bottom Bracket

Shimano Ultegra 6800 Bottom Bracket Cups SM-BBR60
Bottom bracket cups for Shimano Ultegra FC-6800 Hollowtech II cranksets. Approx. 14g lighter with reduced friction compared to the SM-BB6700.

Features a smaller cup design for improved weight and performance.

⚠️ Note: Due to the smaller cup size, some older bottom bracket tools require the Shimano TL-FC25 adapter (sold separately).
