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.

Materials & Dependability

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

Proportional Sizing Syncs Bar Width & Grip Size

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.
