The story of the H21 begins with its material. Canyon utilizes a high-modulus unidirectional carbon fiber layup. But let’s peel back the jargon. "Unidirectional" means the carbon fibers run predominantly in a single, continuous direction along the length of the bar. This is critical for a flat bar because the primary forces are linear: you push down, you pull back, and you twist against the steering axis.

We spent two months testing the H21 against Canyon’s standard H17 alloy bar on a Canyon Roadlite. Here is the subjective performance breakdown.

Many versions of the H21 are designed to work seamlessly with modern cable routing systems, keeping your cockpit clean and aerodynamic.
