Size

Description

The Coefficient AR Handlebar is engineered to optimize your position and performance on the bike, whether you're tackling your daily commute or an all-day epic. Our unique aero-ergonomic design combines a precise slope and sweep (what we call SWOPE) to put you in a more comfortable and efficient riding position. This isn't just a slight improvement; it's a difference you can feel, translating into better speed and endurance with less fatigue. You're not just buying a handlebar—you're upgrading your entire riding experience.

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 technical specifications, a 38cm bar has a much smaller grip diameter than a 44cm bar.

Lightweight Materials

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.

SWOPE Design

SWOPE is our unique bar-top shape combining downward slope and rearward sweep to place your shoulders, arms, and wrists in a more natural position. This greatly improves metabolic, ventilatory, and aerodynamic efficiency.
