CXWXC Adjustable MTB Stem 31.8mm 70 Degree - 90/110/145mm Bike Stem Riser for Handlebar - Aluminum Alloy Mountain Bike Handlebar Riser Extender for MTB Road City Bike Bicycle (31.8 x 145mm)

The CXWXC Adjustable Stem (31.8 × 90mm) completely transformed my ride. Installation was quick and straightforward, and the wide adjustment range made it easy to dial in the perfect upright position. The build feels solid and secure on my e-bike—and the improvement in comfort was immediate. Wrist, elbow, and back strain are basically gone, and I finally feel relaxed and in control while riding. If you’re looking to improve comfort and posture without changing handlebars, this stem is an absolute must-buy.

This little stem is fantastic! I bought the 110cm for my gravel bike. The reach to the handle bars was hurting my low back and I want the bars to be closer and to sit more upright. I measured and after installing and the bars are now 2 inches closer and 3 inches higher! Such a simple and inexpensive fix. Highly recommend this item, if you’re hesitating about buying, don’t. Just make sure to measure your brake cables..I still have plenty of slack but had I bought the next size up, 145cm, I may have had to replace the cables with longer ones.

I was nervous at 1st because I was putting this on an Ebike but it is super sturdy and strong. Haven't had ANY issues with this product! Love it!

I recently purchased the CXWXC Adjustable MTB 31.8mm 70 Degree - 145mm stem for my Aventon Level 2, and I must say, it has been a game-changer for my riding experience. This stem fit my bike with a minor modification, making it the perfect height to raise the handlebar almost 3 inches without the need to replace any wires. The installation process was relatively straightforward, with the only hiccup being the remounting of the headlight. The CXWXC mount where the existing light mount attaches was slightly larger, requiring me to make a small adjustment. I ended up cutting one of the mounting holes off the light mount to allow it to snug up to the new stem mount. To secure everything in place, I used two of the original short bolts to attach the handlebar to the stem and one of the new long bolts to attach the light mount onto the 4th hole of the stem. Despite this minor inconvenience, the end result was well worth it. Overall, I am extremely satisfied with the CXWXC Adjustable MTB stem. It has provided me with the perfect height adjustment I needed while maintaining the integrity of my bike's existing components. If you're looking to upgrade your ride and enhance your comfort level, I highly recommend giving this stem a try.

Got this for my Lectric X 2, to move the handle bars up and back a little bit. It was relatively easy to install with one problem. It needs a spacer for the stock handle bars to work. They did not include a spacer/adapter. I made one out of PVC pipe I found in my junk pile and it works no problem. It was my oversight. There are units with the adapter included out there. Overall a really nice upgrade I wish I had done sooner. Solves the handle bar problem with my Lectric X2.

Perfect for raising my handlebar to the exact right height for me. Not too heavy. Fits perfectly.

Very well made with good range of adjustment. Not too heavy but adequately strong. Made my biking less painful. Very good buy.

This riser did a great job giving me the rise I needed and is easily installed and adjustable.

Doet perfect aan de eisen

Does the job. Allows me to move handle bars up and bring them forward. Much more comfortable riding position now. Good quality and easy to fit.
