RockShox Crown/Steerer/Uppertube Assembly

Replacing the entire assembly is often the only way to fix bent or damaged stanchions, as they are permanently pressed into the crown. This unit ensures the alignment between the steerer and the tubes remains factory-perfect, which is critical for smooth suspension travel and steering precision.

No, this assembly features a tapered steerer tube. You must ensure your bike's headtube is compatible with a tapered steerer before purchasing, as it will not fit a standard straight-steerer frame.

No, this is strictly the upper assembly, which includes the crown, steerer tube, and stanchion tubes. You will need to transfer your existing lower legs, air spring, and damper internals to this new unit.

No, this assembly is specific to 120mm of travel and 27.5-inch wheels. Changing these dimensions requires different parts, and attempting to mix components with different travel or wheel size specifications will compromise the fork's geometry and performance.

Compatibility is determined by the stanchion diameter, wheel size, and axle standard. Since this unit is built for 32mm stanchions, 27.5-inch wheels, and Boost axle spacing, you should verify these specs against your current fork's serial number or service manual to ensure a match.
