Coefficient RR (Road Race)
Carbon Handlebar

The Coefficient RR handlebar is purpose-built for riders that race frequently on pavement and/or gravel.​

Price: $399.00

 

Garmin or Wahoo GPS Mount are included with every RR.

Ideally Suited For:

  • Road Racing & Chasing City Limit Signs
  • Aggressive Gravel Riding & Racing
  • ITU Draft Legal Triathlon Racing

The RR’s patent pending integrated computer bridge is not just a perch for your favourite data capturing gizmo, it offers hand placement options to powerfully and comfortably lift you over a steep climb AND/OR stretch-out and narrow-up to bridge a gap or breakaway from the pack. Designed within UCI and ITU rules, the Wave RR will change your cycling experience for the better.

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. With a deeper drop and increased rigidity, the RR promotes a more aggressive, aerodynamic riding position. Our patented Coefficient SWOPE (sloping, sweeping bar tops) carries over from the AR to relax your upper body and improve respiratory and neuromuscular function.

The RR Bar is Shimano Di2 compatible. It not only accepts the bar end junction, it includes exit holes for remote shifter buttons in four locations (2 each side) on the underside of the tops. The RR bar is engineered to be a plug and play solution: the reach and drop are the same or within a few mm of most current road bars. This means your current stem length and height will normally stay the same if you are changing to a Coefficient handlebar.

Note that internal cable routing of both shifter and brake [hydraulic or cable] is possible, but not necessary; cables can be routed under the bars as you would do so with a traditional bar. In some cases, new cables or hydraulic hoses may be required to route the cables internally through the handlebars.

Lightweight Materials & Dependability

When comparing handlebar weights keep in mind that the average off-the-front computer mount weighs in at 30 to 40 grams. The Coefficient RR is moulded using Toray unidirectional carbon fibre and tested to ISO international standards for professional road racing.

In partnership with Bar Fly Bike, the Coefficient RR includes your choice of the following cycling computer mounts: Garmin, Wahoo, Lezyne, Polar, Cateye, Bryton, Joule, Hammerhead, Magellan and Mio. We also offer a GoPro camera mount that attaches to the underside of the computer bridge. Replacement mounts can be ordered as well.

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.

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.
