2024 and newer cross-country models moved to WP's closed-cartridge fork, which takes a different kit: see Upgrading WP's closed-cartridge fork. The compatibility finder confirms which fork your bike has.
Ways to improve it
From the least to the most of the fork replaced:
| Option | What changes | Good first step when |
|---|---|---|
| Air pressure and setup | Air pressure for your weight, sag, oil level, clickers | The fork has never been set up for you |
| Revalve | A tuner rearranges the stock shim stacks for your weight and terrain | Setup is right but the damping isn't |
| Cone-valve mid-valve | The compression shims under the mid-valve in the damping leg are replaced with a machined cone and spring | Square-edged hits, braking bumps and landings still spike and deflect the front |
| Coil conversion | The air spring is replaced with coil springs | You want a coil spring's feel instead of air |
| New cartridges or a fork swap | The fork internals, or the whole fork, are replaced | You want a different fork altogether |
The Tintic cone valve for the Xact air fork
The WP Xact - Tintic Reds CV Upgrade is a drop-in replacement for the mid-valve in the Xact's damping leg: $364for one valve, and one valve does the full bike. A machined cone and spring take the place of the compression shims. It's machined and assembled in Pleasant Grove, Utah, and comes with an install reference card.
A qualified suspension tuner installs it in about 90 minutes, normally during a standard fork service, and sets it up for your weight and riding. Many riders have it done alongside a revalve. Find a tuner on our dealers page.
