Looks good, works as designed, light weight nice quality and easy to install. Comes with the needed tools to mount this to your bike. Quick installation good value for the money. One thing to note is if you have non-typical handlebars like I do, you need to be sure of the tube size of your bars to ensure the fit. Typical handlebars are 31.5mm my bars are 35mm so didn’t fit the bike I originally ordered this for but still worked out for using on my road bike.

Allowed me to make the adjustments I needed, at an affordable price. No need to over engineer these things and drive price up. This works perfectly.

Nice way to raise the handlebars on a MTB. I ordered two for our bikes, but had to return one because it was a thicker size. Amazon says that this is a frequently returned item and I would guess there being two different sizes is why, so make sure you check the diameter of your handlebar prior to ordering. Very solid and appears to be a high quality item. I would say the price is fair for what you get.

My first stem's bolts had striped out so I bought this to replace the stock stem, after putting it on my bike and riding it for awhile and I noticed that the adjustment bolt keeps losing up especially if the ride is bumpy. Once I get a torque wrench I will tighten it all the way.
