LinearXL air spring and Charger 3.2 RC power the BoXXer Select 27.5in Boost Fork

What Our Gearhead® Experts Are Saying:


"This fork hits the sweet spot for riders building a serious DH setup. The linear spring curve keeps the bike predictable through braking bumps, and the damper is easy to adjust between track conditions. It feels stable at speed without being harsh."


On steep, technical downhill tracks, consistency creates speed. The BoXXer Select 27.5in Boost Fork is engineered around LinearXL, a position-sensitive air spring that maintains a linear force curve through the travel. By reducing speed sensitivity and managing lower leg air behavior, it delivers predictable mid-stroke support and controlled end-stroke performance with a jounce bottom-out system.


The Charger 3.2 RC damper is tuned to complement the LinearXL spring, providing speed-sensitive control with independent rebound and compression adjustments. Its virtually silent operation keeps rider focus locked on terrain feedback. The 38mm chassis balances stiffness and compliance to minimize deflection without transmitting excessive vibration, preserving traction through rough sections.
