Kbrotech Bike Handlebar Extender Double Handlebar Extension Carbon Fiber Mount Holder with Aluminum Alloy Bracket Space Saver

I received mine yesterday. Literally a half hour after I unboxed it, it was installed. And that includes the time I spent obsessively measuring everything to ensure that the mounting clamps were perfectly centered on the extension and divided it into three perfectly equal sections. (I worked with engineers WAY too long. LOL!)I experienced none of the slippage described in other reviews. That said, mine is centrally mounted on a road bike handlebar that flares out toward the center mounting point. Also, the handlebar itself has a black "matte" finish that may help the spacers grip better than they might on a chrome plated or other highly polished handlebar. After I tightened the clamp bolts, the extension didn't budge; it's as solid as can be. I used the thinner spacers/gaskets; a thicker set is included as well.Interestingly, the extension itself is a fairly small diameter. I don't know whether this is "standard" or not; it probably, because the Cycliq Fly12 I mounted on the extension includes a thicker spacer for its handlebar mount that allows it to fit perfectly. But it's something to be aware of. If the components you're going to mount on the extension don't come with spacers to allow mounting on a bar that's 31.8mm/1.25inch in diameter (approximately 100mm/4inches around), you'll have some work to do.All in all, this extension is a perfect fit for my bike, and does its job admirably. It was probably the easiest, most straightforward installation of any component I have ever put on any bike. When it comes time to outfit our other bikes with an extension bar, this is definitely the one I'll get.Finally, I should note that I have absolutely no relationship with Kbrotech other than that of a highly-satisfied customer.

So I bought this so I could a bag to the handlebars. It arrived very expediently from the US.The bar is light weight which it's meant to. You don't want to add too mych weight to your handlebars as it is. Easy enough to install eventually. I just found it fiddly because my handlebars aren't one size. I would have given it 5 stars except it needs a variety of rubber inserts with different thickness for it to fit different sized handlebars. Definitely would recommend.

Didn't fit bike

The description for this is wrong as my headline states. The tube is aluminum (I know that for sure since it was scratched on a burr) with carbon fiber "finish" the grip rings are hard plastic not the grip rubber you would expect.I needed this thing to work so I just got left off the plastic rings which tended to slip out of place and used handlebar cork, my handle bar is tapered where I wanted to mount the tube brackets so this worked better anyway.Using the cork it is held solid with all my accessories on it, I do like that the bracket is hinged so with the bolt out if flips wide open making using the cork or rubber easy.As I mentioned earlier the tube was scratched on bit on the end so you may want to run some fine sandpaper on the inside edges of the bracket and take the bolt out and pry open a bit.I have to give it 3 stars because the description is off but it is light and functions well and looks good too

Is very lightweight and seems sturdy once installed, justifying its value for the money. The only complaint I have is that the clamps that attch it to the handlebars are too perfectly matched to a single size, which happens to be about 2mm larger than my handlebars. This necessitated making shims of the proper size, which in turn made it quite difficult to hold the clamp in position in order to start the screw. Once it was installed, though, it seemed very rigid. Overall a good buy.
