RockShox Crown/Steerer/Uppertube Assembly

Replacing the entire assembly is often necessary if the steerer tube is damaged or if the stanchions have developed play within the crown. Because these parts are pressed together at the factory to ensure precise alignment and structural integrity, replacing the unit as a whole is the safest and most reliable way to restore your fork's performance.

This assembly is designed for specific RockShox models with 32mm stanchions and 29-inch wheels. You must verify that your current fork lowers match the specific chassis generation and axle spacing (110mm Boost) of this assembly to ensure proper fitment.

No, this is a bare crown/steerer/uppertube assembly. It does not include the air spring, damper cartridge, or the lower leg assembly, so you will need to transfer those components from your existing fork.

While it is possible to perform this swap at home if you have the correct tools, it requires specialized equipment like a bearing press and a fork seal driver. If you are not comfortable with suspension service, we recommend having a professional mechanic handle the installation to ensure everything is aligned and torqued correctly.

This assembly is compatible with forks having 130-150mm of travel. However, the actual travel of your fork is determined by the air spring assembly inside, not the crown/steerer unit itself, so your travel will remain whatever it was previously.
