Shimano BBES300 bottom bracket

Description

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

Does Not have a Direct Mount
