  • 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

  • Cartridge design allows easy installation without adjustment
