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.

Build quality is as expected for a cheap product. It does look cool but I would pay more money for real carbon fiber or metal. The brackets are aluminum. Overall it works and I’m happy. It does what it needs to.

used on my e bike so I could have 2 lights on my aventon step through it has weird odd shaped bars so I got 2 of these so I could put a led light bar and a nitecore light on it

I bought this to space out a bar bag from the frame and use as secondary mount for lights. Concept is great, but implementation is horrible. I know it is a low cost item, but it is very cheaply made. One of the screw holes stripped out on the initial installation. I managed to get it secured with a little finesse, but had some concerns about long-term integrity. Those were eliminated once I tried to mount things to the bar. The bar diameter is ridiculously small. Nothing clamps to it, even with spacers. I tried spacers inside of spacers which didn't work. I suppose you could try adding rubber sheets in layers, but this results in a wonky set up. Also, the bar ends are flush with the OD of the bar. This means a bar bag attached with Velcro or straps, can easily slide off. You can try to adjust strap spacing or clamp location on the bar but, for me, this didn't work from dimensional constraints. Not only I would not recommend this product, but I believe this is a waste of resources.

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

Nice addition to my bike, works as advertised

Well packaged. On time, described good. Worth the price.

It’s very lightweight and pretty durable. The clamps are a bit fiddly, but I think that’s just the normal nature of them in general. It’s really hard to get the spacing right depending upon your handlebar size. I needed to use a little bit of outdoor electrical tape and then skip their larger shim. That’s a top tip for any view considering any thing on your bicycle. It also helps protect the bar.

Looks nice.Coulda been a inch or 2 longer but it will serve its purpose and it was dramatically cheaper than most others

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.

I ride a small frame and when fitting my sleeping gear (tent, matt, pillow etc. inside a compression bag) to the bars it hits the front wheel. I tired a few solutions but this has been the best option so far. Angled up, I cinch the bag to the handlebars and extension bar keeping everything away from the front wheel. Tested over few days bikepacking over bumpy fire roads, it hasn't slipped.

It took two weeks to deliver. Amazon delivery is not what it used to be.

It’s not for the heavy item like Swytch battery which is about 3- 4kg max. The battery keep slipping down a bit while riding. It would hold small items like phone, lights etc not a problem.
