Ride character of the Forbidden Druid 2020
In size L, the Forbidden Druid 2020 pairs a 65.6° head angle that splits the difference between descending calm and quick steering; a compact 445 mm reach that keeps it flickable; a relaxed 73.3° 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.
