It's awesome. I bought the longest one, it's so nice and comfy to ride now. I love it.

fit like a glove ....easy to install

Works great! Makes my 30yr old Trek MTB rideable again! Super easy to install. Build quality and fit were perfect.

Know your size! I purchased this for an e-bike and as usual everything is made for a guy 5.5 feet tall. I'm 6-1 and the seats and handlebars are always too low to fit my leg length. So I put these to raise the bar. I also usually buy seats and stems. As this was for an E-Bike I did not take into account the length of the wiring on these new e-bikes - so I could only use half the height of this stem to allow some play in the electrical wiring from the handlebars to the frame of the bike. For other e-bikes, I have taken apart the electrical wiring to reroute them to allow for more height for the handlebars. KNOW YOUR HEIGHT

Fit as it should… easy to install

Very sturdy. Easy to install.

The riser will enable you to raise your handlebars up higher, so you don't have to bend down to reach them. I bought the long one (180mm length) and raised my handlebars to a comfortable height. However, I don't have them at the highest position for now, but if I decide to go higher, that is still a possibility, or lower if I want, because of the versatility in the extra length stem. Any height is possible depending on how you arrange the spacers and handlebar clamp on the stem.

3 days trying and I gave up trying to get it to work. Couldn't get the adjustment right. Either too loose or too tight, I think I'm pretty mechanical but this has me stumped. I'd think I got it then it would loosen up, after about 29 attempts to get it right I went back to the original and within 5 minutes my old one is set up perfectly. It's NOT me.
