This front suspension fork is designed for mountain bikes with extra-large frames. Featuring a 180mm travel air spring and 9mm QR axle, it provides smooth damping over rough terrain. The 1 1/8-inch straight steerer tube fits most standard headset configurations. Manual lockout allows you to stiffen the fork for paved sections or extra support when needed. Dual shoulder axle clamps and tapered lower legs increase strength. Black powder-coated finish holds up well to outdoor elements. An ideal upgrade for e-bikes or heavy-duty mountain rigs, this suspension fork helps absorb bumps so you can focus on the ride.
