The Shimano BBR60 Ultegra BSA Bottom Bracket is engineered for cyclists who refuse to compromise on performance. When you're pushing your limits on challenging climbs or sprinting for the finish line, every ounce of weight and every bit of friction matters. This bottom bracket delivers where it counts—providing a noticeably smoother pedaling experience that translates directly to more efficient power transfer and longer-lasting components.
At just 14 grams lighter than its predecessor (the SM-BB6700), the BBR60 proves that sometimes the smallest changes yield the biggest results. The compact ball bearing design keeps weight low while maintaining exceptional durability. You'll feel the difference in your first ride—less resistance means more watts reaching your wheels, whether you're attacking steep gradients or maintaining a steady pace on long-distance rides.
The anodized bearing cups provide superior protection against the elements and wear that comes with aggressive riding. This isn't just about weight savings—it's about creating a more reliable, longer-lasting drivetrain system. When you're miles from home or pushing through the final miles of a century ride, you want components you can count on. The BBR60 delivers that peace of mind with construction that matches the legendary Shimano quality you've come to trust.
Engineered specifically for Shimano Ultegra (FC-R8000, FC-6800) and 105 (FC-5800) groupsets, as well as Metrea (FC-U5000) and CX70 components. This means optimal performance and perfect fit right out of the box. No compromises, no adjustments needed—just install and experience the immediate difference in smoothness and efficiency that will have you wondering why you waited so long to upgrade.
For cyclists who demand the best from their equipment, the Shimano BBR60 Ultegra BSA Bottom Bracket represents an essential upgrade that delivers tangible benefits you can feel from the very first pedal stroke.
