  • Discreet and effective.
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. ... show more

  • Very light and compact, strong enough for everything except your actual hands.
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. ... show more

  • Works with a little work !!
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. ... show more

  • Accessory attachment point for handlebar bag
I buy two of these for each bike then double up the clamps which makes everything very solid. The tubing is small diameter for most of my accessories, but it is typical for most bike accessory mounts like this. I just add bike tire tubing or wrap on handlebar tape to increase the diameter of the tubing. Because I double clamp everything, I have had no issues mounting accessories. I ride 4-5K miles a year so this product gets used extensively. ... show more

  • Sent USED bar
I really like this bar, mainly bc my handle bars are very thin and these are able to clamp down significantly better than another brand on Amazon. My wife has the other brand on her, equally thin, bars and those just kept sliding. After examinations, the clamping design for these bars are much better then the other brand. I ended up purchasing a 2nd set of these bars. The reason for not giving 5 star is I was sent a set of bar/clamps that were CLEARLY used and a bit worn. The bar has deep scratches where it was tightened by the clamps. Some of the items that came with my first set were missing with these (fortunately i didnt need them). When I received my first set, i did have suspicion it was used, or at least test mounted elsewhere before being sent to me. It wasn't enough to be sure they were used but now i'm sure they were. Wouldn't recommend to anyone as i'd guess they would ship a used part. Maybe its a trend for people to use these and return, but looking at the mount, I'm sure i can find another brand with similar design . ... show more

  • Outstanding Product
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. ... show more
