UPANBIKE Bike Rest Handlebar Aluminum Alloy Aero Bar TT Bar for MTB Mountain Bike Road Bicycle Triathlon Time Trial

Please exam the photo I submitted as it highlights the exact weakness of this product. As mentioned in other reviews, this product was delivered a bit scuffed, even with a deep zig-zag scratch near the end of one bar. But what can you expect when the package had no kind of protection other than wrapped in a thin plastic bag?The highlighted points in my photo represent the tightness problem everyone has described. Luckily, if you're a bit practical, you can resolved these issues with some ingenuity. For the larger clamp that attaches to the handle bars, I used a washing machine hose, cut to just over the width of the clamp, and in half to sandwich the handlebars. This provided extra security that the stock even with completely useless shims couldn't provide. For the upper clamp that attach the speed bars to the brace, I used some vinyl tubing and performed the same operation as I did with the handlebar clamp.The hoses can be purchased at any nearby hardware store for cheap (you're likely going to have a lot of material left over), and the entire process of fitting was easy.Absolutely and unequivocally the manufacturer is at fault for such poor engineering and production. The shims are completely useless, and the elbow/forearm rests are non-adjustable (fore and aft, yaw can be adjusted slightly). But with some ingenuity, not bad for the price.You pay for what you get. But if you're practical, the price is decent for what you get.

Can’t beat it for the money. I was pleased to find a nice set of aero bars for this price. I am a beginner to triathlons so, clip on bars to my road bike was a good start. They have been pretty comfortable so far.

After about 400 miles, the pads holders stripped out. Can't figure out if this was because of vibration or because of pressure.

This should be a pretty easy clamp to make and be reliable but even after torquing more than I should have needed to I could still move the bars with not very much effort. Would have been a good deal if that wasn't an issue. As they are right now I would not recommend buying these

I purchased for my spin bike. Would never put on my triathlon bike for the road. The hand bars are not secure to the elbow rest. Any bump would make them move all over. You get what you pay for

Can't get them tight enough so there is some movement to them. I am using them for my indoor cycler so it is ok but would be dangerous riding outside with them

I installed the product and torqued it up with a torque wrench. The screws however slip out and the first time I tried to use the product, it slipped, causing me to crash. Fortunately, I was on a bike bath away from automobile traffic. The old adage of "you get what you pay for," is true here. Buy a reputable one from a bike shop and you might be able to use it safely.

The only really bad thing is there is no tilt to the elbow pads, which make it near impossible to dial in the angle

Good quality for the price. The one issue I have is that they slip at the interface between these bars and my handlebars. I can't tighten them enough to prevent some slippage.I don't see an easy fix for this. If they had serrations (or something similar) to prevent slippage they would tear up the surface of the handlebars where these bars attach.On the plus side, I was worried tightening these excessively would strip the threaded aluminum parts. No sign of this being an issue.

There are all kinds of reasons that I like this. It's bit heavy, but very comfy. It has a bunch of ways to adjust it so that you can fine tune it. The curve in bars make your hand conform to it in a much more natural way. But... if the perfect place to mount it onto your handlebars happen to be where handlebar changes diameter, then forget it. There is no way to mount it securely. A deal breaker. Unfortunately, I had to return it.

These are junk. Right-hand bar mount stripped before it would even go tight, left hand elbow pad mount stripped before it would tighten as well. I wouldn't use these even if they did, they are not safe. Save your money and buy a name brand.

even if you're not supposed to hold it too strong, it slips too much, I wasn't able to lock anything firmly (from the bar to the holder itself). I'm considering sending it back.
