FOMTOR 31.8mm Adjustable Stem 90mm 0~60 Degree UNO 31.8mm MTB Adjustable Handlebar Stem for Most Mountain Bike Road Bike (Fit for 1.25'' Handlebar)

Seems to be good quality, fit properly, looks good, and does the job. Lifted and moved my handle bars back making for a much more comfortable ride.

Really like how this stem raises the handlebars and adjusts for my arm length. I no longer get a sore neck or shoulders after a long ride. Also, I appreciate the ease of return/exchange from the seller. Even though there are multiple warnings in the description about ordering the right size; somehow I managed to order the wrong size. Actually, I have two identical bikes and was ordering a second stem. I googled Uno 820 and didn't realize the "820" wasn't a specific size. I was able to return the wrong part and order a correct one with no hassle.

Overall, I'm glad I got this; it does make my riding position more comfortable. But I assumed it would allow me to get the handlebars higher and closer. Also, and I knew this in advance, it required me to move my headlight because this stem is designed differently than the one that came on my Aventon Aventure. Not sorry I made this purchase.

It might look ridiculous to have my handlebars this way, but it is SO much more comfortable! I’m only 5’3” so a 26” bike is almost too big for me and the original handlebar placement was way too far away. Now I can sit up while I ride and not put any pressure on my wrists. I originally ordered a longer 130mm version but it was way too long for my e-bike wires, plus the placement just wasn’t good, the handlebars either were too close to too far away. This 90mm version is great and I had no trouble installing it myself.

My seat was killing my perineal area. In trying to figure out why, I was able to tease out that my handlebars were set such that they made me lean forward. That leaning forward, forced my perineal area into an uncomfortable positioned onto my seat. With the style of handlebars on my Giant Commuter bike, there was no way to change/adjust the handlebar position. I did a lot of research and located this adjustable post. I switched out the old handlebar post (a SIMPLE procedure) for this one, set the angles I needed and it is PERFECT for me now. Much less expensive than a new bike and it works very well. I am no longer leaning into the handlebars. That was VERY painful. The only concern with any part that is adjustable, moveable and handles the total steering of a bike, plus handles your full weight against it, is to make certain EVERY TIME YOU RIDE that the screws (allen wrench style) are tight. If they are tight, you will not have any issues with the bar working loose. With regular checks for tightness, the bar will not accidentally move on you, which would be disastrous. I would highly recommend this item. There are choices in length when ordering. Take care to really analyze exactly what you need to fix your issue. This was a a pain saver for me. Completely changed my biking world. I give it 5 huge stars.
