Ride character of the Specialized Stumpjumper 29 2020

In size L, the Specialized Stumpjumper 29 2020 pairs balanced 437 mm chainstays that keep it lively without feeling nervous; a 66.5° head angle that splits the difference between descending calm and quick steering; a compact 445 mm reach that keeps it flickable; a relaxed 74.1° 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.
