## Description

Review: EXCELLENT PRODUCT - ORDERED FOR FAMILY MEMBER
Review: 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.

## Questions & Answers

**Q: Is this strong enough to hold a handlebar bag for bikepacking?**
A: I only have two lights on mine, but I believe it could hold a handlebar bag quite easily.  Maybe not loaded with 10 lbs. worth of stuff, but it is really sturdy.  Give it a try.

**Q: What is the center to center dimension between the handle bar and accessory bar?**
A: No one answered as it is a not a clear question. It is obviously going to vary depending on shape of your handlebars and where you mount it on the curves of your handlebars. Maybe one in 100 handlebars are perfectly straight. Center to center I can have 1.5 inch to 2. inches depending on where mount clamps as well as how you have handle bars themselves mounted

**Q: Would it work for my 4wheeler handlbars**
A: Measure the diameter, as long as that fits then it should work.

**Q: The description shows that the length of the bar is 202 mm, which converts to 7.95”. Is this accurate, One review said that it is only 6”?**
A: Just put a tape on mine and it is 8 inches long, so 7.95” would be within the accuracy of my quick measurement.  We are very satisfied with the bar and mounting system.

### ⭐⭐⭐⭐ Works with a little work !!
*by O***E on July 19, 2020*

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.
