Suspension character of the Giant Reign 29 2020

The Giant Reign 29 2020 runs Giant’s Maestro four-bar suspension. As our MTB suspension kinematics guide explains, the linkage type only sets what is possible, what actually defines the ride is the bike’s leverage curve, progressivity and anti-squat, not the name of the system. Set your sag at the wheel rather than only at the shock (on progressive frames the two differ), aim for anti-squat near 100% in your common gears for efficient pedalling, and use the rebound curb test to dial damping. Read this bike by its numbers, not its badge.

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.
