Gravity Fsx 1.0 26" Aluminum Mountain Bike Frame: Dual Suspension

The Gravity FSX 1.0 is a 26-inch full-suspension mountain bike frame built from custom-formed, TIG-welded 6061 aluminum. Its CantiBeam Link single-pivot suspension design provides active rear travel that helps smooth out roots, rocks, and rough terrain on recreational trails. The included KS coil-over rear shock features adjustable preload, letting riders dial in the suspension feel based on their body weight and the terrain they plan to ride. Disc brake mounts ensure compatibility with modern braking systems for reliable stopping power in wet and muddy conditions.

This frame ships with several key components already included—a headset, seatpost clamp, and the rear shock—reducing the number of additional parts needed to complete a build. The replaceable rear derailleur hanger is a practical touch, as it allows for an inexpensive repair after a crash rather than replacing the entire frame. With 135mm rear hub spacing and availability in four sizes from 15 to 21 inches, the FSX 1.0 provides a versatile platform for building a budget-friendly full-suspension mountain bike. It is best suited for riders who enjoy casual to moderate trail riding and want the comfort and control that dual suspension provides over a hardtail frame.
