AzarxisBike Fork Stem Bicycle Extender Handlebar Riser Adaptor Aluminium Alloy Head up Adapter Flexible Easy Installation for 1-1/8 Inch 28.6 mm Mountain Bike, Road Bike, MTB

Probably one of the best things ever for a mountain bike that the handles cant be adjusted, no more hunchback! No longer have to lean forward when riding it feels nice, thought i wasnt going to be able to fit the entire attachment on but i was able to just perfectly, without messing with the brake cables on my mongoose limestone 28”, someone complained about no instructions, but the instructions are literally on the photo gallery for the item, so just have ur phone by you, good product im satisfied

Works well

I spent all this money on an e-bike that I liked except after riding my back was always sore because the handlebars were too low. Went on Amazon and found this extender which promised to fix the problem. The good news is that it totally delivered as promised. Worked perfectly. The only reason that I didn't give it 5 stars is that it doesn't come with any instructions. It was somewhat intuitive but still took me 5 minutes to figure out how to do it. Turned out that the hardest part of process was finding the right size Allen wrench. Once I figured it out it took less than 5 minutes and as I said it's a great fix....just ordered another to do my second bike.

I purchased couple months ago this handlebar riser and it has truly transformed my riding experience. The sturdy extender fits perfectly with my 1-1/8 inch bike neck and was a breeze to install. The additional height adjustment it provides has made a noticeable difference in my comfort and posture, especially on longer rides.Highly recommended for both casual riders and serious cyclists alike who are seeking a more comfortable and ergonomic riding position!

Installs quickly and easily and puts the handlebar on my Trek Domane 2 bike in a much more comfortable position. Seems really well built.

Excellent quality. Fits well.

I bought this handlebar riser for my mountainbike because I no longer need the more aggressive stance that the bike offers. This nicely machined extension fit my bike perfectly and changed my riding position to one more in keeping with the riding I now enjoy.The installation of this riser did not require any changes to the bike or its components...it fits, it works and it is a good looking addition to the bike.I wholeheartedly recommend it to anyone looking for a more comfortable, upright, riding position.It's money well spent.

The two screws to the stem and undersized compare to the original stem clamp bolts so I can understand some reviewers indicated the screws stripped. Looking in the stem attachment, noticed there is less cross sectional material to carry load through the stem . I see potential stress machined stress risers that could lead to a stem crack or failure. Looks like the unit was drilled by the clamp area to reduce likelihood of cracking.....not possible to tell if the material was heat treated as indicated. Some stems extensions are forged alloy which may be a better bet.
