Product information "ULTEGRA SM-BBR60 Hollowtech II BSA bottom bracket TOP-DEAL"
Shimano Hollowtech II SM-BBR60 BSA bottom bracket for Ultegra FC-R8000/6800, 105 FC-R7000/5800 and GRX FC-RX810 cranksets (without original packaging).
The HOLLOWTECH II technology concept was designed to produce an optimised crankset that minimises the effort required by the rider for the drivetrain. The high rigidity of the crankset ensures efficient power transmission when pedalling, while its low weight takes the strain off the rider, especially on longer journeys. The crankset was developed with a view to optimising the ratio between stiffness and low weight. HOLLOWTECH technology enables extremely light, hollow crankarms that are manufactured using SHIMANO's exclusive forging technology to maximise stiffness. In addition, the HOLLOWTECH II crankset has the right crank firmly connected to the axle of the bottom bracket, which achieves an optimum balance between maximum stiffness and minimum weight. The externally mounted bottom bracket offers better weight distribution and more stability, which ensures more efficient power transmission
Features - Shimano SM-BBR60 BSA
