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.
