Fox Unveils the All-New 34 SL: Unequalled XC Capability

Fox is redefining what’s possible for short-travel mountain bikes with the introduction of the all-new 34 SL. Designed for the most technical World Cup XC courses, and to match the increasing demands of these short-travel riders, the 34 SL brings unprecedented capability to a full-width 34 chassis with up to 130mm of travel — all while maintaining a World Cup race weight.

The new 34 SL builds upon the legacy of the class-leading 34 Step-Cast, delivering enhanced stiffness, improved suppleness, and more travel. With the demand for 130mm travel growing among XC riders, Fox engineers developed a fork that pushes the limits of short-travel suspension performance.

Key Innovations:

• Full 34 Chassis – Unlike the Step-Cast design, the 34 SL utilises a full 34 chassis with a larger volume air spring, allowing riders to choose from 110mm, 120mm, up to 130mm of travel without compromising weight.
• More Travel – Now available in 130mm, without a weight penalty, the new 34 SL gives you the suspension advantage to climb faster, descend harder, and recover quicker, so you can keep the hammer down.
• Redesigned Arch and Crown – A generatively designed arch increases torsional stiffness by 17% over the previous 34 SC, while increasing tyre clearance. A new 7000 series aluminium crown features larger internal bores and an anodised finish to further reduce weight.
• Increased Bushing Overlap – With 20% more bushing overlap than the 34 SC, the 34 SL delivers enhanced smoothness giving riders better tracking through rough terrain, especially at higher speeds.
• GRIP SL Damper – Designed specifically for short-travel applications, the GRIP SL damper optimises pedal-to-bump efficiency, ensuring a lightweight package with unparalleled ride feel.
• GRIP X Damper – Available in the 130mm chassis, the GRIP X damper brings trail-forward capability to the 34 SL.
• Inboard Bypass Channels – Relocated from the aft side to the inboard side, the bypass channels improve small bump sensitivity and reduce dynamic friction for a more responsive ride.
• Weight Optimisation – Featuring the ultra-light Kabolt SL axle (-12g), double-butted stanchion tubes (-9g) and refined full-width lowers, the 34 SL weighs in at just 1475g (29” 130mm GRIP SL) - 40g lighter than its closest competitor.

The Future of Short Travel

Built to meet the needs of modern XC racers, the 34 SL sets a new benchmark in lightweight, high-performance suspension. Whether tackling the gnarliest World Cup XC tracks or pushing the limits of short travel bikes, the 34 SL delivers stiffness, responsiveness, and weight savings in a class of its own.

Lightest XC Ecosystem

When you combine Fox SL parts - 34 SL, Float SL, Transfer SL - you get the lightest overall complete XC suspension and dropper system from any leading brand, 333 grams lighter than our closest competitor with equivalent spec, and 489 grams lighter than the competition’s electronic XC system, both of which offer a maximum 120mm travel fork vs. Fox’s 130mm max travel.

When it comes to weight, Fox’s SL ecosystem is by far the lightest. And with more travel.
