The Coefficient RR handlebar is purpose-built for riders that race frequently on pavement and/or gravel.
Free Computer GPS Mount with every RR for every retail customer: Please specify which mount you need when ordering. NOTE: Order the same size handlebar that you usually ride. So if you ride a 42, then order our bar in size 42. And keep the same length stem!
Note we have a quantity of 44cm bars that cannot be internally routed. These are available in the drop down at a reduced price.
Ideally Suited For:
- Road Racing & Chasing City Limit Signs
- Aggressive Gravel Riding & Racing
- ITU Draft Legal Triathlon Racing
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. It's also compatible with SRAM Blips.
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.
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 the highest ISO international standards for professional road and mountain bike racing.
