CoefficientRoad Race Carbon Handlebar(Return to Product Page)

Bought these for a new aggressive gravel build. Internal routing is a PITA, but it looks great when done. Finish/craftsmanship on these bars is top tier. Positions are all fantastic and really enjoy, they are definitely stiff. Coming from Lauf Smoothie bars (the only bar I've ever used that has noticeable comfort/compliance), these are definitely stiffer and I found myself dropping some front PSI for comfort - as they're intended to be a road race bar, this makes sense, but something to consider. Price is also steep, but they are a one of one product offering so is to be expected.

An expensive way to gain a little comfort. The tops are quite comfortable with the slope going from high in the center to low at the drop and forward to back slope to match, the natural hand position is quite comfy. Due to the shape you end up reaching further for hands in the center/tops position. A shorter stem might be needed...but that will compromise your hoods and drops position. There is a little bump at the lowest outward point of the tops that allows you to "rest" the grip a little. Is it a game changer, no. Despite the prolific YT videos. Its still a carbon handlebar. Heavier than less expensive normal bars. Routing the cables was fairly easy. I don't feel like my Garmin sits level on the fixed computer mount. With the lower drops level, it seems as though the leading edge of the Garmin is a little lower than the trailing edge of the Garmin, effectively tilting the unit away from me.

In the end, buy if you like the shape and features. If you want less weight and less cost, another option will work just as well.

This is the second bike I've converted to these bars. If you climb while on the tops, you will immediately note more relaxed wrists, with more tucked in / aero elbows. There's a couple of indentations on the drops that really work for me. Whatever the reason, I'm more comfortable in the drops than with any other bar I've ridden. The pseudo-time trial / aero bar front triangle is also comfy and useful. For SRAM AXS people, I note that I've added blips that lie just under where my index fingertips are. Since I shift more when climbing than generally, this is perfect. No need to change hand position when shifting from a top hold.

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.

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!

I bought this handlebar to put my wrists and arms into better alignment. I use the tops quite a bit more than when riding a round bar. I don't get as much pressure on my hands, and my wrists aren't sore after a ride. The price is significant, but if you can afford them, I highly recommend this product. Check out Coefficient Cycling's website for detailed information.

Thoughtfully designed handlebars, the swept back design is comfortable and aero (at least for me), drops are shallow with thumb rests. Works well with blip shifters on the tops. Very pricey, but BTD has them on sale periodically

The bar puts your hands in a more comfortable position.

I have had several bars over the years. These bars are the most comfortable I have ever had.

They are worth the price.

Awesome comfortable bars

Awesome bars! Bar None, the most comfortable bars out there very lite weight and great for any riding, road or gravel .

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.

I use it on a gravel bike that doubles as a road bike. The SWOPE tops are the biggest improvements over a traditional/aero drop bar. I find myself on the tops a lot more due to the comfort. The notch for the thumbs in the drops are a neat feature too. Elsewhere on the bar are similar to a traditional bar in terms of shape and comfort in my opinion. Expensive, but there are some comfort gains. Installation requires longer brake hoses due to the additional extension/bends, but fairly straight forward.
