## Customer Reviews

### ⭐⭐⭐⭐⭐ Light light light
            
*by B***W on November 7, 2018*

Wow! This thing is light!Same bend as my stock bar, but less than half the weight. I took a half-round file and radiused my stem at the edges, to eliminate any sharp edges or ridges that would compromise the bar. Looks good, feels great!
  

### ⭐ Not 31.8mm (slightly smaller)
            
*by K***L on April 7, 2019*

I was so excited about these handlebars. While I was installing, I noticed that my stem bolts had to be screwed down super tight to stop the bars from moving around. Bad sign. Then, I nearly stripped the bolts on my lock-on grips while trying to tighten those. I gave up on the whole project when I realized my brake and shift levers couldn't lock on to the bars whatsoever. Even when they were screwed on as tightly as possible, they still slid around. These bars are not the standard 31.8mm MTB bars. Don't bother.
  

### ⭐⭐⭐⭐⭐ Significant improvement in ride comfort
            
*by D***A on June 18, 2019*

My commute involves riding an unpaved section. Without front suspension and with aluminum handlebar, lots of vibration was going into the hands, which was unpleasant. After installing this carbon handlebar and a carbon stem, ride quality has improved quite a bit - more than I expected. I am now enjoying riding that section.
