Ride character of the Rocky Mountain Instinct BC Edition 29 2020
The Rocky Mountain Instinct BC Edition 29 2020’s handling comes down to its geometry, reach, head and seat angle, chainstay and wheelbase, balanced for its category.
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.
