Nice quality. Like the ability to make it almost vertical. Mounting piece is a little on short side. Needed to add a spacer to stem to fit propertly.

I installed this on my 2017 Specialized Sirrus which I converted into an E-Bike. I wanted to ride in a more upright position. This CYSKY Bike Stem worked out well, it adjusts close to 90 degrees more like 85. The stem is very well built and looks good too. I did have to use the included spacer (universal ) because my handlebars are 25.4mm diameter. The spacer seems to clamp well with no squeaks or vibration. After the installation of the CYSKY Bike Stem I can ride upright, my hands don't get numb anymore and an added bonus is that the bike handles better because the stem is not angled towards the front of the bike. This is a very nice bike stem!

Well made adjustable stem riser. Great to raise the handlebar to a more comfortable position without having to replace or lengthen the shift or brake cables.

My one complaint about our Lectric XP3.0 Ebike was the distance the handlebars were away from our seated position. The stem allows the handlebars to be brought closer to our seated position. This allows a more comfortable upright riding position.
