Coefficient blended volumes of anthropometric and ergonomic data with real-world advice from professional bike fitters and coaches, as well as feedback from professional and amateur cyclists. The result is a better handlebar for better performance.

Both the AR and RR feature Coefficient aero-ergonomics that make it easier to ride faster on the noon ride or an all-day ride. Literally dozens of prototypes are buried in the Coefficient AR bar boneyard. The Coefficient SWOPE (Slope + Sweep) combine to provide a more comfortable and efficient ride that translates to improved performance, especially on longer journeys.

The Coefficient AR Handlebar is molded using Toray unidirectional carbon fiber and tested to the highest ISO international standards for professional road and mountain bike racing.

Riders of smaller stature generally have small hands. Proportional sizing is all about the grip diameter of the Coefficient AR's tops. As you’ll read in the chart, a 38cm bar has a much smaller grip diameter than a 44cm bar.
