Ride character of the YT Decoy 29 2020

In size L, the YT Decoy 29 2020 pairs long 458 mm chainstays that plant the rear wheel for stability and climbing traction, at the cost of some playfulness; a steeper 655.0° head angle that keeps the steering quick and efficient; a moderate 462 mm reach; a low-slung bottom bracket (~37 mm drop) that corners with confidence (mind pedal strikes).

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.
