Blackbearing Wave Washer

The Blackbearing Wave Washer is designed to provide smooth and precise crankset clearance adjustment for 24mm and 30mm axle cranksets. It ensures perfect alignment without adding unnecessary pressure on the bearings, maintaining long-term performance and smooth rotation.

Optimized for 24mm and 30mm Axles: Compatible with both 24mm and 30mm crank axles, this corrugated washer adapts easily to different bottom bracket systems. It helps fine-tune crank preload, ensuring a snug fit while preserving the natural movement of the bearings.

Prevents Bearing Stress: The wave design allows controlled flexibility, which compensates for minor variations in assembly tolerance. This eliminates bearing compression and reduces friction, resulting in longer bearing life and smoother pedaling efficiency.

Durable and Lightweight Design: Crafted from high-quality spring steel, the washer maintains consistent tension and shape over time. Its lightweight construction adds no unnecessary weight while contributing to stable crank performance.

Ideal for riders and mechanics seeking precise setup, the Blackbearing Wave Washer is a simple yet critical component that enhances drivetrain smoothness and ensures your crankset runs effortlessly mile after mile.
