Splined bottom bracket for use with Shimano Octalink chainsets.
- Oversize BB spindle - large 22mm diameter hollow cold forged chrome-moly pipe billet spindle reduces weight, increases strength and rigidity
- Octalink splined axle/crank arm interface - results in more rigid crank assembly compared to square tapered spindle
- Sealed cartridge assembly with oversize ball bearings - maintenance-free high-efficiency rubber seals keep out dirt, mud, and water
- Cartridge design allows easy installation without adjustment
