What sets the Ultegra SM-BBR60B apart

Compared to entry-level models, the Ultegra bottom bracket offers smoother rotation and increased longevity. The integrated seals effectively protect against dirt and moisture, extending maintenance intervals. The low weight of just 119 grams positively impacts the overall bike weight.

Ideal for ambitious cyclists and home mechanics

This bottom bracket is particularly suitable for road bikes, cyclocross and gravel bikes with BSA bottom bracket shells. Mountain bikers aiming for a lightweight and efficient crankset also benefit from the high-quality workmanship. Installation can be done yourself with the appropriate special tool (sold separately).

How to mount the bottom bracket

Unscrew the old bottom bracket from the frame. Clean the threads thoroughly. Insert the new SM-BBR60B with the BSA thread hand-tight and tighten it to the specified torque using the Shimano mounting tool TL-FC25 (not included). Observe the bearing installation direction.
