Upgraded Super73/Ridstar/Mac Fox Front suspension

Applicable Models: Fits most 20" x 4.0 fat-tire snow bikes, beach bikes, and e-bikes — check your crown lockout, QR spacing (9mm x 135mm), and disc brake compatibility before ordering.

Lightweight: Magnesium and aluminum alloy fork legs with an imported air spring rod bring it down to roughly 2,645g (±50g) — about 1.8 lbs lighter than a comparable oil-spring fork.

Adjustable: Manually dial in the air suspension's firmness to match your riding conditions.

Travel: 180mm of travel keeps things smooth over snow, sand, and potholes.
