Coefficient AR (All Road) Carbon Handlebar
The Coefficient AR's unique shape and proportional sizing optimize how riders interact with the front of their bicycle.
We 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.
Ideally Suited For
- Endurance Road Cycling & Racing
- Gravel Riding & Racing
- Cyclocross
- Bikepacking & Touring
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.
