BB-ES300 bottom bracket 68 - 113 mm

Splined bottom bracket for use with Shimano Octalink chainsets

• Oversize BB spindle - large 22 mm 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
