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

ORDERED FOR FAMILY MEMBER

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.

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.

This was a piece of cake to install and adjust. The cf is amazingly light weight. I have an electronic bell on main handlebar of my stand-up e scooter, plus oem bell, so I use this for my bike light with rubber strap. I can still add another accessory or two, although I don't have a need to get a phone mount. I'm sure I'll come up with something else. The cf bar definitely adds to the look of my scooter. I would purchase this again if needed, w/o reservation.

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.

Not sure what they were thinking when they designed this. The clamps the ago in your handle bar are standard 31.8 cm so that works fine on lost handlebars. But the the additional bar that apparently is to mount things such al lights is a much smaller diameter. Hence any thing that is designed to mount to a standard handlebars will not work. In fact the diameter is so small that I could not get any of my lights to work on this. I am not sure what the thinking is here, what is its function suppose to be? It is sturdy and mounts just fine, so if you can figure a use for it then it is OK

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

Love the look, the feel, cost was great! The length fits perfectly on my bike and I’m able to mount 2 lights and a switch. The functionality works well, can adjust forward or back depending on preference. The durability seems great as it is made of aluminum brackets and the pipe is carbon fiber. Would highly recommend!
