Ride character of the Specialized Stumpjumper 27.5 2020

In size L, the Specialized Stumpjumper 27.5 2020 pairs balanced 432 mm chainstays that keep it lively without feeling nervous; a slack 65.5° head angle that stays composed when it gets steep and fast; a compact 435 mm reach that keeps it flickable; a relaxed 75.0° seat angle.

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.
