FOX suspension fork 29" 34 SL Performance Series Grip SL 3 Pos. Adj 120 mm BOOST 44 mm Offset tapered black | 2026
Incomparable XC performance. Lightweight. Stiff. Fast.
The 34 SL sets new standards in the cross-country and downcountry segment. With its striking, beefy 34 chassis, it combines unrivaled XC performance with a suspension travel of up to 130 mm. Specially developed for the most technically demanding World Cup routes and challenging downcountry tours.
The 34 SL is the first choice for those who ride the borderline between XC racing and aggressive trail riding - light enough to win, tough enough for everything after.
Features
- Increased stiffness for precise line choice and control
- Light & robust: Lower weight than the 34 Step-Cast, with more stiffness
- Top performance: Sensitive response for maximum control
- Versatile: Perfect for fast XC races and technical trails
Crowns the fork
The crown made of 7000 series aluminum is characterized by a perfectly developed structure. The outside has been machined, while larger holes on the inside provide additional weight savings.
Casting
The new triple clamp developed by FOX engineers for the 34 SL improves torsional stiffness by 17 % compared to the previous 34 Step-Cast XC fork. At the same time, targeted cut-outs have made it possible to save weight without compromising the stability of the fork tubes.
GRIP SL damping
An ultra-light, short-stroke damping system that offers an unrivaled ride feel in its class. It offers a particularly sensitive response and optimized efficiency without annoying bobbing. In lockout mode, the integrated blow-off function ensures that unexpected impacts are reliably absorbed.
Float Evol Air Spring
The Float EVOL (short for Extra Volume) air spring is a special technology from Fox that is used in forks and shocks to improve response and spring characteristics
Air Volume Spacers
The FLOAT air spring can be fine-tuned by using volume spacers to make your suspension element more progressive or linear.
Performance Elite
Black is Beautiful. The same technologies and adjustment options as the Factory series, but without Kashima. Performance Elite is (almost) on a par with the best.
Kabolt SL Axle
The Fox Kabolt axle is a lightweight thru-axle for Fox forks in 15 mm standard (100 mm or 110 mm Boost). Developed with racer Geoff Kabush, the lightweight upgrade was created as a replacement for conventional quick-release axles.
