Wheels Manufacturing Wave Washers

A wave washer is designed to apply a specific amount of axial tension to the bottom bracket bearings. This tension eliminates side-to-side play, ensuring the crankset rotates smoothly without unwanted movement.

No, these are specifically engineered for cranksets that utilize a 24mm spindle, such as Shimano Hollowtech II systems. They are not suitable for 30mm spindles or other oversized axle standards.

Yes, it is best practice to apply a light layer of waterproof bicycle grease to the washer before installation. This helps prevent creaking and ensures the washer can properly seat and adjust against the bearing seal.

You should only use the number of washers required to remove play from the crankset. If you have already installed the crank and feel lateral movement, add one washer; if the crank feels stiff or binds when tightened, you likely have too much tension and should remove a washer.

These are considered a consumable shop item. Because they can deform over time or get lost during maintenance, having a ten-pack is a practical way for home mechanics and shops to keep their drivetrain service kits stocked.
