Gravity Fsx 1.0 26 inch Dual Suspension Bike Frame - Aluminum

The Gravity FSX 1.0 is a 26-inch dual-suspension mountain bike frame built from custom-formed, TIG-welded 6061 aluminum with hydroformed tubes in the front triangle. Its CantiBeam Link single-pivot suspension design pairs with an included KS coilover rear shock featuring adjustable preload, allowing riders to dial in sag and firmness to match terrain and riding style. Disc brake mounts on both the front and rear ensure compatibility with modern braking systems for reliable stopping power on steep descents and wet trails.

Practical details make the FSX 1.0 a solid foundation for a custom build: a standard 1⅛-inch head tube accepts widely available headsets, the 68mm English-threaded bottom bracket shell works with most cranksets, and the 27.2mm seatpost diameter and 135mm rear spacing keep parts sourcing straightforward. A replaceable rear derailleur hanger means a trail mishap won't retire the frame, and the included 31.8mm quick-release seatpost clamp rounds out the package. Available in four sizes from 15 to 21 inches, this frame gives riders the flexibility to build a personalized full-suspension mountain bike around proven aluminum construction.
