Flip chip in rear dropout has two positions: short and long. Flipping the chip changes chainstay and wheelbase length by 10mm.
Note: Geometry based on 160mm fork.

Ride character of the Santa Cruz Megatower 29 2020
In size L, the Santa Cruz Megatower 29 2020 pairs balanced 435 mm chainstays that keep it lively without feeling nervous; a slack 65.0° head angle that stays composed when it gets steep and fast; a moderate 470 mm reach.
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.
