The handlebar is ok, but if you are using aero bars, this handlebar is not going to work very well.  I am using Profile aero bars and because the handlebar is larger in the center and then tapers to a smaller diameter, the aero bars are loose all the time.  T
here isn't a non-tapered sec ion of the handlebar to clamp to.  This isn't a fault with the handlebar, it's just something I should have considered before ordering it. I will probably replace this handlebar with something that does not have the taper.

Chrome is nice. The fit is a little tight and there's no internal liner, so by design, it bites the handlebar a little wherever you mount it. So make sure it's where you want it, one time. Other than that, it's a good piece.

It's bigger in diameter than I thought, but that's probably my fault.  I also didn't understand the different handlebar sizes at the time, so it didn't fit the bike I intended it to fit, but I was still able to make use of it on my other bike.  Seems loud enough!

Looks nice, is wonderfully lightweight, BUT be aware that the part that clips onto your handlebars is made of solid steel rather than the hardened plastic I was expecting...this means it's not elastic at all and you have to make sure that your handlebars are a small enough diameter that you can just slide these things over them.

Mine were not, so I ended up returning them.

they don't tighten onto the handlebar that good and vibrate down, also the mirror vibrates makes it somewhat hard to see into mirror.

Yeah, ok. It is what it is. Be sure you're able to lift your bike.

I purchase this stem to raise my handlebars. I wanted a more upright riding position. Having a two bolt clamping setup for the bars is nice. The stem maybe a bit high for some people, so take some measurements first.

It'll get the job done for people who aren't that picky. i didn't want anything fancy or really expensive or PRE-owned. the handlebars rock just a tad and so does the seat itself. haha. but whatevs. i'm not like, too annoyed by it.

These grips are fine, but I strongly recommend a wider bar without bar ends if you're mountain biking.  The control and ergonomics are much better that way, which is why I returned these.

Nothing wrong with the quality, feel, or design.  I just think bar ends are so last millenium, and the MTB community agrees.

Sits too high above bike handlebar (3 inches) causing unsafe handlebar wobbling when one hand is removed from bar for turn signal, using water bottle, and other necessities. A design that sits on the handlebar is preferable for better bicycle handlebar stability and safety; and aerodynamics for that matter.

sweet handlebar, is very wide so your bike is more stable, the color looks even better than it looks  in the pictures. Also is very light weight for its sizes.

Handlebar-Grips doesn't have an option for an adjustment for different Handlebar diameter and it is horrible. not really smart to not have it otherwise it is Okay.

It doesn't seem to take much to break the clamp that attaches to the bar.  I broke the first one (definitely my fault for dismounting the bike via the handlebars), but then the replacement broke the same way (at the hinge) rather unexpectedly.

The mount is metal and isn't the easiest to clip on particularly if you have thick handlebars.  There is no give at all in the mount.

OK, but not great, the bracket sticks out too far from handle bars, so I rigged without the bracket.

the product comes with a 'cheap' quality handle bar bracket, and not large enough for my Harley Fatboy, but I used the other attachment and it worked fine, the construction is fine.
