World Cup XC speed. Downcountry capability.
The FOX 34 SL Factory brings lightweight race performance to a full-width 34 mm chassis, delivering the stiffness and control demanded by today’s increasingly technical XC courses and aggressive downcountry bikes.
Built around FOX’s lightweight GRIP SL damper, the 34 SL delivers a supple, controlled feel while maintaining the pedaling efficiency racers demand. The 3-position adjustment provides Open, Medium, and Firm compression settings, allowing riders to quickly adapt the fork for climbing, racing, and technical terrain.
FOX’s redesigned 34 SL chassis increases torsional stiffness by 17% compared with the previous 34 Step-Cast, providing more precise steering and confidence when pushing hard through technical sections. A lightweight 7000-series aluminum crown, FLOAT EVOL air spring, Kabolt SL axle, and Factory Series Genuine Kashima Coat complete the race-focused package.
Starting at just 1,503 grams, the 34 SL offers an impressive combination of low weight, stiffness, travel, and control for modern XC and downcountry riding.
