Overview

The Gravity FSX 1.0 Dual Suspension Mountain Bike is built around a custom-formed, TIG-welded 6061 aluminum frame with hydroformed tubes and an oversized bearing CantiBeam link single-pivot rear suspension design. Both the SunTour front fork and the KS coil-over rear shock offer adjustable preload, giving riders the ability to fine-tune the suspension response for their weight and the terrain ahead. This dual-suspension layout absorbs roots, rocks, and trail chatter that would otherwise be jarring on a hardtail, making it a solid option for riders looking to explore trail riding without the premium price tag of higher-end full-suspension platforms.

Stopping duties are handled by Tektro Novela mechanical disc brakes with 160mm rotors front and rear, delivering more consistent braking than rim brakes in muddy or wet conditions. The 24-speed drivetrain pairs Shimano Acera and FD-M190 derailleurs with Shimano EZ Fire trigger shifters and a 22/32/42T crankset, providing a broad gear range that covers steep climbs and faster descents. The bike rolls on Maddux DX221 double-wall aluminum rims wrapped in 26x2.1-inch multi-tread tires, and details like the Cane Creek sealed-bearing headset, WTB Speed V Sport saddle, and Formula forged aluminum disc hubs round out a specification sheet that punches above its price class for a full-suspension trail bike.

Pros & Cons

👍 Pros

  • Full dual suspension with adjustable preload on both front fork and rear shock absorbs rough terrain effectively
  • Mechanical disc brakes provide reliable stopping power regardless of weather or trail conditions
  • Lightweight 6061 aluminum frame with hydroformed tubes keeps weight manageable for climbing
  • 24-speed Shimano drivetrain offers a wide gear range for both steep climbs and fast descents

👎 Cons

  • Assembly is required out of the box, which may be challenging without bike mechanic experience
  • Entry-level components like the SunTour fork and Tektro Novela brakes may need upgrading for aggressive trail riding
  • At 26-inch wheels, the bike uses an older wheel standard that limits future tire and wheelset upgrade options
  • Coil-over rear shock adds weight compared to air-sprung alternatives found on higher-end full-suspension bikes
