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:
- 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.
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.

Customer Reviews
Was using an Enve SES before from an old bike. Going allroad now the tops were really unfomfortable on gravel.
So I gave this bar a try and loving it thus far...the back-downswoop is increadibly comfortable to where I even go to the tops when Im just cruising here and there.
I picked the 36 version so the tops are rather short but its enough to get a few different grips in.
Really enjoy the bar
Great look and handling.
After two years of wanting it, its about time to build a new bike with all the top components i love and that bar was up high that list.
Havent install them yet, waiting for the rest of the parts but it looks and feel so perfect and comfortable.
One thing i should mention that ive noticed, when mounting a wahoo element roam, it does leave some mark on twist part surface with the bar, not a scratch, but its noticeable. Other than that its perfect.
Everything ok.
Upon having seen and read several reviews of the bar I decided to order one for my race bike. I'm 48 years old and starting to experience some aches like numbness in my hands or pain in the wrists when riding 4h or longer. The order process went smoothly and the delivery was fast. The bar was well packed. The customer service was exceptional and excellent as I forgot to order a set of spare grummets and I had to submit a second order. The day after the second order of the grummets I received an email in which I was told that a refund for the shipping fee was already initiated. That was very thoughtful and forward thinking and not to be expected. After installation of the bar I don't regret the purchase. The bar feels very comfy. I haven't experienced any problems in my hands or wrists so far. The additional weight of 100g compared to my former bar is a trade I'm happy to accept for the higher comfort. The overall ergonomics are really great, the notches for the thumbs in the drops feel very natural. In short I enjoy every bit of the bar and I would highly recommend it to anyone looking for a new bar. Thanks for the great product.
