Gravity Fsx 1.0 FSX 26" Dual Suspension Bike Frame

The Gravity FSX 1.0 is a dual-suspension bike frame designed for 26-inch wheels, built from custom-formed TIG-welded 6061 aluminum alloy. Its oversized-bearing CantiBeam link single-pivot design provides a straightforward and reliable suspension platform for trail riding and general off-road use. The frame comes equipped with a KS coil-over rear shock featuring adjustable preload, letting riders dial in the suspension feel to match their weight and preferred riding conditions. Disc brake mounts are standard, and the replaceable rear derailleur hanger is a practical inclusion that simplifies repairs after trail mishaps.

As a frame kit, the FSX 1.0 includes several components that reduce the parts list for a custom build: a headset and a 31.8mm quick-release seatpost clamp come in the box. The 135mm rear spacing is compatible with standard 26-inch mountain bike hubs, giving builders flexibility when selecting wheels. The 68mm English-threaded bottom bracket shell accommodates widely available cranksets. While the frame requires a separate fork, wheels, drivetrain, brakes, seatpost, and bottom bracket to become a rideable bike, it offers an accessible entry point for riders who want to hand-pick every component of their mountain bike build.
