For downcountry riders who want more descending control than an XC damper gives, the 2027 Fox 34 SL Factory pairs the light 34 SL chassis with the trail-optimised GRIP X damper.

Highlights

• Updated for 2027
• GRIP X damper, revised to approach the ride feel of GRIP X2 with 120g less weight
• 130mm of travel, the most the 34 SL chassis offers, with a 44mm offset
• Genuine Kashima Coat 34mm upper tubes
• 17% more torsional stiffness than the 34 Step-Cast

Full-width 34 chassis, XC weight

The 34 SL brings real XC capability to a full-width 34 chassis with up to 130mm of travel, built for technical XC courses and downcountry riding. Its generatively designed arch wraps around the lowers to raise torsional stiffness by 17% over the 34 Step-Cast, and the externally machined 7000 series aluminium crown, with larger internal bores, shaves more weight.

GRIP X damper

This version runs Fox's trail-optimised GRIP X damper. Fox updated it to approach the ride feel of GRIP X2, and it is now quieter and 120g lighter than GRIP X2.

Fitting and Fox service

Fork installation is a separate workshop service and isn't included. As an authorised Fox service centre, our Marrickville workshop can fit the fork to your bike (steerer cut, crown race and star nut), set sag and damping for your weight and riding, and look after its scheduled Fox servicing from there.

Compatibility & fit

For 29in wheels with a 15 x 110mm Boost hub (Kabolt SL thru-axle) and a 1.5in tapered steerer. Axle-to-crown at 130mm is 540.5mm. The crown suits 58mm head tubes only. Brakes are 180mm post mount direct, up to 203mm rotors with the right adapter. Maximum tyre size is 29 x 2.5in. Fox rates the 34 SL for EN 17406 category 4 use with a maximum system weight of 121kg, and lists it as compatible with Class 1 and L1e-A e-bikes. Check your frame's allowable fork travel before you order.
