Product Details

Overview & Technology

Wheels Manufacturing Wave Washer (24mm) is a compact, high-precision spring washer engineered to remove side play in cranksets and to help pre-load angular-contact bearings. Manufactured from hardened spring steel, each washer compresses from an uncompressed thickness of 2.1mm down to 0.5mm under load, giving a controlled, repeatable preload window for 24mm spindles. The Wave Washer's curved profile stores elastic energy to maintain axial pressure between crank components without relying on friction alone. That makes it ideal for fine-tuning bearing preload and eliminating small amounts of play after installation or over time as parts bed in. Always follow your crankset manufacturer's placement instructions when installing wave washers to ensure correct function and avoid over-compression.

Key Features & Benefits

Material and durability: Made from spring steel for reliable, long-term elastic recovery and corrosion resistance when used with typical drivetrain greases. The material choice balances toughness with consistent spring rate so the washer keeps pressure without deforming permanently. Precision dimensions: Designed specifically for 24mm spindle systems, the Wave Washer provides a predictable compression range (2.1mm → 0.5mm) which simplifies setup when shimming or adjusting preload. Supplied as a 10-piece pack (WAVEWSH-24MM-10) for multiple installations or spares in your toolbox.

Fit, Compatibility & Installation Notes

The Wave Washer is sized for 24mm axle/spindle interfaces — commonly found on many Shimano Hollowtech II cranksets and other 24mm standard cranks. It is intended for use where manufacturers specify a thin wave-style shim to control side play or to preload angular-contact bearings. Check your crankmaker's manual for exact placement; incorrect placement can lead to improper preload or bearing damage. Installation tips: clean mating surfaces, apply a light film of grease to prevent corrosion and noise, and compress the washer only as directed. Because the washer compresses significantly under load, only small visual gaps will remain once the crank is torqued to spec. Keep spare washers on hand — they’re small, inexpensive, and often saved for service or race-day adjustments.

Who This Is For

Road cyclists, mechanics and shop techs who demand precise bearing preload and elimination of crank side play will benefit from this Wave Washer. It's ideal for riders who service their own Hollowtech II style cranksets or maintain a fleet of bikes and need a reliable, repeatable shim solution. Also useful for bike shops, race crews and home mechanics who want a compact, long-lasting part to fine-tune crank bearing feel without replacing bearings prematurely. Supplied as a 10-pack so you can keep extras for multiple bikes or emergency repairs on the go.

Frequently Asked Questions

What does a wave washer do on my crankset?

A wave washer provides axial spring pressure to remove lateral play and correctly preload angular-contact bearings. It compresses under load to maintain consistent contact between the crank spindle and bearing races, improving bearing life and eliminating slop.

Is this wave washer compatible with my 24mm Hollowtech II crank?

Yes — this washer is sized for 24mm spindles commonly used on Hollowtech II and other 24mm crank standards. Always confirm your crank manufacturer's instructions for washer placement and whether a wave washer is recommended for your specific model.

How many wave washers should I use per crank?

Follow the crank manufacturer's guidance; many setups use a single washer on one side to fine-tune preload. The Wheels Manufacturing pack includes 10 washers so you have spares for service or multiple bikes.

Will the spring steel corrode or lose its spring over time?

The Wave Washer is made from spring steel designed to resist permanent deformation under normal use. Like any steel part, it can corrode if exposed to moisture and salt — use a light grease film during installation and inspect parts periodically, especially in wet or winter riding conditions.

Can I use this washer to tighten a loose crank instead of replacing bearings?

If the only issue is minor side play, a wave washer can often correct preload and restore tightness. However, if bearings are rough, noisy, or have significant play, replace the bearings rather than relying on a washer to mask underlying wear.

Where should the washer be placed during installation?

Placement varies by crankset — some manufacturers specify the washer between the crank arm and bearing cover, others between spacer stacks. Always refer to the crankset installation manual for correct location and torque specs to avoid over-compression or improper preload.

Buying Guide

When buying wave washers for bottom bracket or crankset preload, start by confirming spindle diameter (this part is for 24mm systems). Check your crank manufacturer’s service manual to see if a wave washer is recommended and where it should be placed. Consider buying a multi-pack so you have spares for repeated adjustments or multiple bikes. Choose spring-steel washers for reliable elastic recovery; note the uncompressed and compressed thicknesses (2.1mm → 0.5mm for this part) so you can predict how much axial movement they’ll take up. If you’re unsure whether to use a wave washer or replace bearings, inspect bearings first — washers correct preload and minor play, but won’t fix worn bearing races.
