Overview
Riding rough singletrack is the target for the Gravity FSX HD 1.0, a dual suspension mountain bike with an aluminum frame, a front fork with lockout and a coil-over shock at the back. It uses a Shimano-based drivetrain with trigger shifters.
Suspension at both ends and disc brakes give an entry rider more control on rough ground than a rigid bike. The limitation is the weight and the need to assemble and tune the bike, and the sizing data in the listing varies.
Who it's for
Off-road cycling on mountain terrain and unpaved trails, with a rider around the height range of the frame. Riders who mostly commute on pavement, or want a lightweight cross-country build, should look at another style.
Pros and cons
- 24 gear range
- Heavy at forty-five pounds
- Sizing data inconsistent
Performance notes
A shock at the back and a fork at the front soak up impacts, keeping the tires in contact on rough ground and reducing hand fatigue. The wide gear range lets the rider spin up climbs and select a taller gear on descents. Disc brakes keep stopping power consistent in the wet.
