The air spring design provides a lighter, more adjustable feel compared to traditional coil forks, making it a strong upgrade option for compatible mountain bike, eBike, youth, and performance bike builds.
This version uses a 9mm x 100mm open dropout axle setup, making it suitable for compatible quick-release style front wheels. The 28.6mm straight steerer is designed for compatible straight steerer frames, while the matte black finish with RST decals gives the fork a clean, performance-focused look.
