## Description

desertcart.com : GUB 31.8MM Double Clamp Carbon Fiber Super Long Bike Bicycle Handlebar Extender Extension Light Lamp Computer Phone Mount Bracket Stand Holder : Sports & Outdoors

Review: 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, desertcart shipped the replacement and had it the next day with all the parts. Very pleased and highly recommend.
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.

### ⭐⭐⭐⭐ Good Quality but Small Diameter Auxiliary Tube
*by M***R on July 31, 2020*

Like someone else here, I bought these to solve space issues with Shimano sub brakes taking up mounting real estate on drop bars. The machined aluminum clamps are well made and went over the 32mm (1 1/4") handlebars with no problem, and they fit nicely between the stem and the brakes. The carbon fiber tube (actual carbon fiber) is very lightweight, but only about 21.5mm (≈7/8") in diameter. This makes mounting clamps that were designed for larger diameter handlebars a bit sketchy, and I was unable to securely attach the strap-on bar mount for my computer which consequently remains on the stem. I carefully removed 47mm (≈1 5/8") from the tube to keep it from interfering with access to the levers (how I know it's actually carbon fiber). I was going to remount the end plug, but decided to use a slip-on cap as it makes a convenient storage spot for something small and light. Quality product. Just wish it had a larger diameter auxiliary tube.
