RockShox Pike CSU

This assembly is specifically designed for 2020 RockShox Pike B1-B2, Select, and Select+ models with 35mm stanchions. Before purchasing, verify your fork's model year and internal designation to ensure a proper fit.

Yes, this is a complete Crown-Steerer-Unit (CSU) assembly. The crown, steerer tube, and upper stanchion tubes are pre-assembled as a single unit, ready for installation into your lower legs.

No, this specific CSU is engineered for 27.5-inch wheel configurations. The stanchion length and geometry are optimized for that wheel size, so it will not work correctly with 29-inch forks.

You will need a standard suspension service kit, including a mallet, a seal driver, and appropriate wrenches for removing the lower legs and air spring assembly. Because this involves disassembling the fork internals, ensure you have fresh suspension oil and grease on hand for reassembly.

No, the steerer tube comes uncut at its full factory length. You will need to measure your current steerer tube or your headtube stack height and cut this new one to match your bike's requirements.

The crown, steerer, and stanchions are pressed together as a permanent assembly at the factory. If the steerer is damaged or the stanchion coating is deeply scratched, replacing the entire CSU is the only safe way to restore the fork's structural integrity and performance.
