RockShox ZEB Select Delta RC Suspension 29" Fork - B1 is a long-travel 29er suspension fork built for modern enduro and freeride bikes that need steering accuracy and calm braking support on steep, fast terrain. The Linear XL air spring targets a coil-like feel—smooth off the top, supportive through the mid-stroke, and controlled at the end of travel—so riders can stay composed when lines get rough and speeds climb.
Tuned around practical setup and predictable trail feel, the Delta RC damper pairs an intuitive compression adjuster with independent rebound control for quick dialing and consistent performance without distracting noise. Stiff chassis details, low-friction internals, and smart fender compatibility make it a strong upgrade for riders pushing bigger tires, bigger hits, and bigger days.
