Shimano ES25 Octalink Bottom Bracket

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

A 2 year warranty is offered with all Shimano products from Chain Reaction Cycles (3 years on Dura-Ace and XTR products).
