Ride character of the Giant Reign SX 29 2020
In size L, the Giant Reign SX 29 2020 pairs a slack 64.5° head angle that stays composed when it gets steep and fast; a roomy 488 mm reach for stability and standing room; a long 1262 mm wheelbase that adds straight-line stability.
Those numbers describe how it steers and sits. How the suspension actually feels, small-bump sensitivity, mid-stroke support and bottom-out ramp, comes down to its leverage and anti-squat curves: see our MTB suspension kinematics guide, and put its geometry head-to-head with any other bike in the geometry comparison tool.
