Get the maximum performance benefits out of your Octalink chainset with the Shimano BB ES-51 Octalink 68mm Bottom Bracket.
This splined bottom bracket has a 22mm spindle, resulting in increased stiffness and strength exactly where you need it most. The hollow pipe design keeps the weight down to a mere 262 grams. The crank assembly is extremely rigid thanks to the Octalink splined axle and crank arm interface, delivering greater performance benefits compared to square tapered spindles.
With an anti-corrosion treatment inside the hollow spindle, this bottom bracket is built to last, and the sealed cartridge assembly keeps dirt, mud and water out. To top it all off, the cartridge design makes the bottom bracket easy to install with no adjustments required.
