Ride character of the Norco Aurum HSP 2019 27.5
In size M/L, the Norco Aurum HSP 2019 27.5 pairs a compact 445 mm reach that keeps it flickable; a relaxed 72.7° 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.
