Ride character of the Giant Reign 29 2020

In size L, the Giant Reign 29 2020 pairs a slack 65.0° head angle that stays composed when it gets steep and fast; a roomy 493 mm reach for stability and standing room; a long 1258 mm wheelbase that adds straight-line stability.

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.

About Us

Bikometry is a discipline focused on the science and art of understanding the geometry and linkage of mountain bike frames and their suspension systems.

This intricate field studies the angles, distances, and details that define a bike's performance on various terrains. Every aspect, from the head tube angle to the chainstay length, influences how the bike behaves.

Linkage, which connects the rear wheel to the bike frame, combined with the suspension, ensures smooth rides by absorbing shocks from the terrain.

By understanding bikometry, whether you're a designer, professional rider, or enthusiast, you can optimize bike performance, choose the right model, or even craft a custom bike. Dive into bikometry with us and explore the nuances that make mountain biking exhilarating.
