Look I made this little project to tighten up my handlebar extenders! It works! It looks great! Also it’s a great value for money! It’s incredibly light weight! The grip is tight! It functions great as a spacer!

It increases the diameter of the handlebar and allows the stem to clamp tightly. A little pricy IMO but does its intended job well.

Not only does it work, but the cool factor to color match is icing on the cake. I knew when changing handlebar riser that I would need a spacer for 1" bars, had a plastic one already but it wasn't thick enough to secure the bars. Was happy to buy anodized red that matched other items on the bike.

Not sure really how else to say this...it works. Fits on your standard handlebars. I'm a small 5'3 female and therefore have tiny T-rex arms. This adapter allows me to use a mountain bike stem with my road bike (drop bars) so that I can have the bars at the right length from me. Just make sure it will actually fit the circumference of your handlebars and you're good to go. Easy installation so 10/10 would recommend.
