Review: Affordable speed - Buy these to see if you like the position. Not a long term investment.
Review: I picked these up for my hybrid bike. The fit was not perfect on the handlebars, they would easily turn and become loose, so I took an old innertube and made little rubber pads for mounting them. Although there is still a bit of movement if I try to turn them, I was able to get them to be tight enough for riding. I find them fairly comfortable for a cheap pair of aerobars. For my purposes they do the trick, but they are by no means a perfect solution.

## Questions & Answers

### ⭐⭐⭐⭐ Review
*by A***G on 14 June 2025*

The only issue I have with these is that they mount very low to the handlebar. So you can get your fingers or hands under them to use that handlebar space. Most of these kind of bars have a riser - these don’t. The result is that I had to mount them onboard on the bars - close together - which wasn’t comfortable for very long ( my elbows were nearly touching when I was down on the aero bars). This was the only way to reserve grip area on the top of the drop bars.
