Find all the Shimano replacement parts you need at Escapa. The Shimano ES 300 Octalink Crankset features an internal hub tube that is a single-piece, cold-forged chromium-molybdenum design. This reduces weight while increasing strength and stiffness. The contact surface between the axle and the crank arm is knurled, resulting in a more secure fit compared to square tapered axles. The sealed cartridge assembly features oversized bearings and a maintenance-free rubber seal that keeps the bottom bracket free of dirt, mud, and water. Its design allows for easy installation without the need for subsequent adjustments.
