Shimano SM-BBR60 Race BSA Bottom Bracket

The Shimano SM-BBR60 is a high-quality Hollowtech II bottom bracket specifically designed for road bikes equipped with Shimano Ultegra, 105, or GRX groupsets. This bottom bracket forms the crucial connection between your crankset and the frame, with Shimano having significantly reduced friction resistance compared to its predecessors. Thanks to improved sealing technology, this component is exceptionally resistant to mud, water, and dirt, which significantly extends the lifespan of the bearings.

The development of the SM-BBR60 focused on an optimal balance between weight and stiffness. With a weight saving of approximately 14 grams compared to the older 6700 series, it offers direct power transfer that is essential for both competitive cyclists and avid touring riders. The compact housing not only provides a sleek look on modern frames but also contributes to the overall aerodynamics and efficiency of the drivetrain.

Installation of this BSA bottom bracket requires a specific adapter due to the smaller outer diameter of the cups. It is a reliable choice for those looking for a low-maintenance solution that delivers smooth performance in all weather conditions. With proven Shimano quality, you are assured of a creak-free riding experience and a tread that continues to perform consistently for thousands of kilometers.
