Dialed Suspension, Your Way

Equipped with an adjustable air spring, external rebound control, and a 2-stage compression lever, this fork lets you fine-tune your setup on the fly. Whether climbing, descending, or cruising in between, you’ll feel the difference in responsiveness and comfort.

At the heart of the fork is our 2CR cartridge, offering smooth, consistent damping and better ride feel across changing terrain.

Strength You Can Feel

The 34mm stanchions and Boost axle spacing create a stiff, confidence-inspiring platform built to handle the demands of modern trail riding. And with our sealed cartridge design, maintenance stays minimal — so you spend more time riding and less time wrenching.
