The RockShox Psylo Gold Isolator RC Fork redefines the mountain biking experience by blending advanced technology with exceptional reliability. Designed for riders who demand precision and performance on every trail, this fork features a robust 35mm aluminum upper tube platform that enhances stiffness and steering control, giving you confidence on technical descents and tight corners. Whether you're tackling aggressive all-mountain routes or cruising local lunch loops, the Psylo Gold delivers smooth, controlled suspension travel ranging from 130mm to 160mm, perfectly adaptable to your riding style and terrain.

Equipped with the innovative Isolator RC damper, this fork offers a three-position compression adjustment—Open, Pedal, and Firm—allowing you to fine-tune your ride for optimal traction, pedaling efficiency, or firmness depending on the trail demands. Complementing the damper is the highly tunable DebonAir air spring, which sits higher in the travel to maintain a consistent, coil-like feel while absorbing impacts effortlessly. The integration of Maxima Plush Dynamic Suspension Lube reduces friction and damper noise, ensuring a silky smooth and quiet ride every time you hit the trails.

Beyond its performance capabilities, the Psylo Gold is built to last with premium bushings that minimize breakaway force and a sturdy magnesium lower leg construction. The fork is compatible with short fenders and includes the reliable Maxle Stealth axle for secure wheel attachment. Approved for e-bike use, it supports a maximum system weight of 373lbs/169kg, making it a versatile choice for a wide range of riders seeking durability and exceptional handling.
