GUB 31.8MM Double Clamp Carbon Fiber Super Long Bike Bicycle Handlebar Extender Extension Light Lamp Computer Phone Mount Bracket Stand Holder

This extender solved my problem: Handlebars with aero routing of cables have little space for accessories. I would have purchased this a couple years ago, but I thought a handlebar extender would span the width of the handlebar and would be ugly. I had little interest in a large, conspicuous product. Thank goodness this product is only wide enough to mount at minimum 3 accessories with comfortable space between. This product makes me smile because you might be able to link more of these extenders together to install even more accessories. So...is it really carbon? I don't know and I don't care. It's light and those handlebar stays are sturdy. One of my photos shows the scratches I put on the bar during installation. If it's a carbon bar, a clear plastic coating protects the bar, but that coating scratches easily. I do not care about the scratches. I expect I will have accessories installed on that bar at all times. My other photo shows there is only 3.5 CM of space between a 31.8mm handlebar and this extender. Those space limitations forced me to install a bike light mount facing toward my seat (and turn it 180 degrees so it would shine forward) because there was no way to install it with correct orientation. You might see some reviews that say this extender fails to clamp the handlebar, which causes it to drop down and become useless. If you have a 31.8 handlebar, you will not need to use the shims and this device will not allow that extender bar to move anywhere. I found this installed quickly and securely. For those of you asking if this extension is suitable as a handle, I would say no. It's just for installing bike accessories and it creates only 3.5 CM of space between your handlebar and this accessory bar. I have purchased 3 other GUB accessories; this company knows milled aluminum handlebar mounts. The greatest compliment I can offer this company is that I am going to buy another one of these extenders for my other bike.

Light weight and stays put. Good quality and have a set for all of out bikes

I needed this bar to add xtra space for stuff on my handlebars. It works great if you can figure out a way to make it stay tight. Great little bar but as other purchasers noted, the screws really suck. They are an odd size and if you put any pressure on them at all they will strip. They strip before the bar is really tightened down and it is almost impossible to get them out. I learned the hard way on the first holder. For the second one I was able to improvise. I just happened to have some machine screws that fit and used them instead of the screws it came with. Made it a little difficult, but after getting in on and tightened down, it works fine.

Very lightweight and easy to fit on the bike's handlebar. The tube is made of carbon. Perfect for adding instruments or for fitting narrower bars while keeping the standard gear and controls.

Fits perfectly on Aventon handlebars and accommodates everything very well. The carbon fiber tube looks awesome, and the mounting brackets worked perfectly, be patient to get the bar positioned and centered just right and tighten it up. FYI, had to send the 1st one back as it was missing 3 out of 4 screws, amazon shipped the replacement and had it the next day with all the parts. Very pleased and highly recommend.

Pro's: Lightweight, can almost fit all bike bars, easy to install Con's: Cheap quality feels like PVC bar, smaller than I thought, will not hold anything heavy.

I'm minimalist on my bike, but in addition to items I always have, such as bell and a couple of front facing lights, on occasion, especially for longer trios or bikepacking I have a bunch of stuff I want out front. And I have little to no room remaining on handlebars of my stock trek 730 setup. Occasionally I want the phone out front, a handbar bag, in some very off the beaten track, a garmin, and sure, why not, a faux pro. So I started looking at these extensions. Many are unnecessarily long, some have small USB power banks and/or integrated headlights. But frankly this "G UB" 20 cm/8" long extension, combined with existing space on my handlebars, is all I need for an entire suite of gizmos plus a good size handlebar bag. i could not be happier. The clamp system is strong enough for weight of a bag with a fair amount of bike tools and stuff, a somewhat heavy 22oz spare water bottle, and a few gizmos. I can set it higher than my handlebars, the same height, or as usually the case, lower, and it does not spin down even on trails. I will recommend you keep track of the rubber shim like pieces since the provided bar is of considerably smaller circumference than most handlebars, and most items will require those rubber strips. But if you do lose track of them, some electric tape, or some pieces from an old tire tube, will work very well. BTW I see in the q/a some people asking about using these as actual auxiliary handlebars. Absolutely do NOT do this as neither the bar piece nor the clamping system are anywhere near as robust as you would need for that. 10lbs of gizmos/bag/water bottle? Yes. But 30, 40, 50, 60 lbs of dynamic weight using them as secondary handlebars? NO.

Light weight and vell made clamps. If you wanted to stack another one on this 0ne, to have Two you would have to have a adapter. I have two stacked. i took thier smaller adapter and ground dowwn the ends enough that tey fit the carbon fiber rod. then i used black electrical tape on the carbon fiber rod where it clamps on to increase it's diameter a little. it took 5 wraps of tape to make the rod larg enough. it clamped down perfect. wrap tape nicely to get a nice looking job.

I got this from a bike packer guy on YouTube and I used it to hold my tent away from crushing my cables and it worked flawlessly. Highly recommended and weighs almost nothing.

This is well made the clamps are machined with precision its a very useful gadget for your bike. Very simple to install. Such a great addition to the bike for all the extra gadgets you want to mount.

Very easy to install. Gives you some extra front bar mounting options. Light weight and pretty strong. Angle and lateral mounting options abundant. Only problem is that they do not include inner spacing rings. My handle bars are very narrow and the mounting ring was way too large in diameter. I had to search around to find a spacer that would grip the handlebar for secure attachment. Big and careless omission on the part of the company. But if you can mount it properly it is well worth the money.

too short, plastic rod, stripped on one side. seriously, 33$...... maybe 5$..

returned, took a shot but obviously its fake carbon
