Coefficient RR
(Road Race)
Carbon Handlebar

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, a Garmin mount is already installed on the bar. In addition, if you plan on attaching a camera or front light to the handlebar, please be sure to order our custom GoPro mount.

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!

RR handlebars are UCI legal. Do note, though, the any use of the middle part of the handlebars as additional point of support will be considered as a violation of UCI Regulation 2.2.025: PART 2 - ROAD RACES (ctfassets.net)

Ideally Suited For: 


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.


Computer Compatibility


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.

After thinking about it for a year and a half, I finally bought it. It's just as I expected. The bike I ride is a Trek Domane, and after riding it about 4 times, I felt that my upper body position was very comfortable due to the shape of the handlebars. The handlebar is slanted slightly below the edge, so it feels more bent, but I think this can be adjusted to by adjusting the height of the stem. It's still winter where I am, so I haven't been able to ride long distances outdoors yet, but I feel like fatigue will be greatly improved during long distance riding. In particular, I am very grateful to the coeffient staff for their friendly response during the purchasing process.
If I find anything better after riding the bike, I will post another review.

Swapped out to this amazing handlebar. Customer service was superb in service and responding.

I bought this handlebar as I have carpal tunnel syndrome after 40 years of working in IT. Ergo fit is ideal, but I am most impressed at how much better the control and sensation in high speed technical mountain descents this bar gives. A very well thought out design.

I built a new bike July 2022 and had trouble finding aero bars to go on the Trek Emonda. Shop had a set of semi-aero FSA bars that I never felt comfortable with.

Finally pulled the trigger on the Coefficient RR bars and instantly fell in love with them. So much comfort, plentiful hand positions, relaxed shoulders and stable at all speeds. Added SRAM blip shifters to the tops making quick and easy shifts.

I'm considering adding these to other bikes in the stable too.

A fabulous addition to the ride. The 'swope' makes sense in the hands. The additional 'semi-puppy-paw' position provides a firm, stable grip while fully aero. Fitted to a titanium Enigma Esprit, I was concerned the advanced visual design might detract from the overall aesthetics. It doesn't. In fact, it rather enhances the look. with several hundred km on the bars so far, I have no hesitation in recommending from both a comfort and a speed perspective.
