FOMTOR31.8 Adjustable Stem 0~90 Degree 80mm MTB Adjustable Bike Stem for 31.8mm(1.25") Handlebar Mountain Bike, Road Bike, Fixed Gear Bicycle, BMX

Ideal component for more comfortable ride

This stem really brings in the handlebar closer and higher towards the rider for a more upright riding position. So in that regard this is better than the adjustable stems that rotates in the front of the steerer.However, this stem is heavier than I had expected. The adjustment is simpler than other similar stems where two adjustments are needed. Perhaps the two adjustment provides a more secure lock?The poor design is in the steerer clamp where in the top of the slit is connected, so this design doesn't allow a free/natural clamping. Unfortunately that section of the stem is not shown in the pictures.In my uploaded picture, see the difference between top and the bottom of the clamps. The top part cannot be fully clamped down because the adjacent part is solidly connected.

I have back issues with my spine. This stem is perfect for adjusting my position while riding my fat tire Ebike. It was super easy to install and I was able to set the perfect angle for comfortable riding.One thing to consider, if you want the stem at close to 90 degrees or at 90 degrees, be aware of the length of your cables for brakes and controllers on your bike. They may be too short to give you enough "play" to raise the stem that high. Otherwise, I recommend this stem. Great product.

I'm a long time rider and my bars were no longer comfortable. This replacement stem allows me to adjust the bars both to raise and bring them closer to me. Still working on the final "fit," but it's clear this item gives me plenty of range in three dimensions.

Pretty nice. My handle bars were really low and this new stem raised them up quite a bit.This will save me from hunching over.Now I can go on longer bike rides.Happy with the product and it is nice to have the option to change angles of the stem.
