Fox 34 CSU

This assembly includes the crown, the steerer tube, and the upper stanchion tubes. It is a complete replacement unit designed to restore the structural integrity of your fork's front end.

Compatibility depends on your specific fork's configuration. This unit is built for 29-inch wheels, 140mm of travel, and a 1.5-inch tapered steerer tube. Always verify your current fork's travel and wheel size before purchasing to ensure a proper match.

Yes, this unit features the genuine Kashima Coat. This finish is designed to reduce friction, providing smoother suspension action and improved durability compared to standard anodized coatings.

Replacing a CSU requires specialized tools, including a crown race puller and a press for the new crown race. If you do not have experience with suspension service and the proper hydraulic press tools, we strongly recommend having a professional mechanic perform the installation to ensure safety.

The crown, steerer, and stanchions are pressed together as a single, permanent unit at the factory. If your stanchions are scratched, bent, or if you have creaking coming from the crown interface, replacing the entire CSU is the only way to safely restore the fork's structural integrity.
