## Customer Reviews

### ⭐⭐⭐⭐⭐ 







  
  
    Great value
  

*by B***S on Reviewed in the United States 🇺🇸 on February 26, 2023*

Bit flexible but I’m very happy

### ⭐⭐⭐⭐⭐ 







  
  
    Super impressed!
  

*by M***M on Reviewed in the United States 🇺🇸 on July 30, 2022*

I’ve use this bar on my time trial bike for over a year now with over 6000 miles on them. So far no issues and they have saved me over 100 g over the stock bars.

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent for sprint bikes.
  

*by M***D on Reviewed in the United States 🇺🇸 on June 26, 2018*

Use on my single speed track style commuter bike (I know, it's weird, but I'm an NYC commuter. All of our bikes are weird or aggressive in some way). I love this bar. Only took it off because I needed drops for those times where I need to get as aero as possible, so I went to carbon drop bars with Tektro RL340 hoods, and use the hoods to sprint.If not for the need for drops, I'd still be on these wonderful bars. They flex backwards only, so only in full track sprint, then they recoil and pull you down on your pedals a little harder. Freaking love em.
