Description

Wow, What Are Those?!

The Coefficient RR (Road Race) carbon handlebar is purpose-built for riders that race frequently on pavement and/or gravel.

Both the RR and it's AR cousin 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. The 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.

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 molded using Toray unidirectional carbon fiber and tested to the highest ISO international standards for professional road and mountain bike racing.

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)

Comfort at a price
by Dan V

I bought these bars for my BMC Teammachine with the hope that they would be more comfortable on long days in the saddle. I bought them during a sale to help reduce the sting of the steep price. Even still, I wasn't sure they would be worth the price of admission. After a few solo climby rides in the mountains and a few longer group rides, I am happy with my purchase. These bars won't magically make everything better if your fit isn't already dialed in. If you're looking for better hand positions and less strain on the wrists/arms when in the tops, then they may be worth it.

I went from 40mm width bars to these in a 38mm width as my shoulders are somewhat narrow. The narrower width is comfortable for me and makes me feel ever so slightly faster - though I'm actually not. The built-in Garmin mount is great for my Edge 840 and the GoPro mount underneath is great for a front light.

A Revolution in Handlebar Design

To test the bars, I did a 45 mile gravel ride with 3K of climbing. I was surprised and amazed how comfortable the bars are. I had a marked reduction in shoulder pain (bone on bone sucks). The back sweep works magically. I rode much more on the tops utilizing the thumb grooves on flats with bent arms in an aero position. I was able to hold this position longer. For climbing, the hands on the tops position was fantastically comfortable and provided a leverage point to pull on. The extreme bend where the hoods and tops meet create a great perch for hands, its a larger than the area on traditional bars. Lastly, the slight flare was perfectly aligned when dropping hands down from the hoods to the drops. I can't speak empirically to the aero benefits but there are plenty of studies that prove the aero design of these bars will save you a few watts. I can say the bars look very cool though!

Common questions answered here! unless your old bars reach and drop are significantly different, No, you don't need to adjust your stem, No, you don't need to adjust your stack height. You may need to tweak the grip position on the bar slightly since the bar has a slight forward tilt. But otherwise, measure the reach on your old handlebar setup; front of the saddle to a point on the shifter grips and also the previous handlebar tilt (digital level is best). The integrated GPS holder is brilliant but with the bars almost level, your GPS will slightly tilt forward (away from you) but using a Garmin 1040, I had no issues reading the screen.

Worth the price of admission

I've had the Coefficient RR handlebar on my 22 Specialized Roubaix Comp since March of 2023 and it has been a game changer. I find myself using the tops of the bar more regularly - which I avoided 100% of the time with the original handlebar. With that, I am able to use all 3 hand positions and am no longer experiencing any hand numbness etc. The comfort it provides long term is well worth the cost - plus... it looks REALLY cool!
