The Shimano SM-BBR60 Hollowtech II bottom bracket is specifically designed to integrate with Hollowtech II chainsets. Its compatibility with Italian threading allows installation on suitable frames, providing secure fitment and efficient power transfer.
The new sealing system significantly reduces internal friction, lowering rotational resistance by about 50%. This results in smoother bearing rotation and improved energy efficiency during prolonged efforts.
The bottom bracket is primarily made from aluminium, offering an ideal balance of lightness and strength. The stated weight is 78 g, which helps limit the overall mass of the chainset/bottom bracket assembly.
Designed for tool-free installation, this bottom bracket simplifies fitting and maintenance. It is intended for cyclosport use and is fitted at the rear with a spacing of 70 mm.
Main specifications: thread Italian, bottom bracket type Hollowtech II, freehub body BCD 104, length 680 mm (provided length reference), colour grey (GRAU). Condition: new.
