At 6'5", I needed a stem that could give me a more comfortable riding position, and the 110mm BUCKLOS stem did just that. The adjustability was key for finding the right fit, and it made a big difference during long rides. It feels sturdy and well-built, plus installation was a breeze. Highly recommend this if you're taller and need to tweak your setup!

This enables a lot of adjustments to location and height of handlebars. As you get older, bending over is harder. Great adaptation

Exactly what i needed to raise my handlebars . My back would get sore with the standard neck, having to lean down on those longer rides. This made riding much more comfortable being able to adjust the height.

I was able to lift my handlebar-height 4 inches with this. Feels even more stable than than it did before. So much more comfortable to ride my bike now. Well worth the money. The installation was a pain obviously, but that's because of my bike, not this stem. I love hoe I can lower it or raise it at any time now!

You have to understand that this stem is not for downhill or enduro bikes. The adjustability comes at the cost of stability. If you go off a huge jump with this, there's a chance it will break more than a higher end quality single piece. It can be even more likely if you improperly tighten the adjustable portion of it. Tighten it too much and you can strip it, too little and it will slip.Yes it is not the lightest of stems but that's ok. It isn't too bad weight wise for what it is. The greatest attribute is of course the adjustable aspect. You can get a more comfortable fitment if the non-adjustable stem isn't fitting you that little bit beyond what's comfortable.The quality seems to be good. I don't see the main pieces breaking as long as it's used as intended. Just make sure you have your cable length in the range if this stem pulls things out more than what your prior set up had.

The BUCKLOS Adjustable Mountain Stem is a great way to raise the handlebars on any bike. It comes in three different heights, all made for 31.8mm diameter handlebars, so be sure your bike has that size handlebar. I ordered the 110mm height, and it made my riding position much more comfortable. I am old enough that a hunched over position is hard on my neck and shoulders, and this gives me a lot of relief. I am about six feet tall and think I would have been better off with the 145mm height, so if you are my height or taller and want an upright riding position, you may want the taller stem extension as well. This stem extension has an adjustable angle, so users can customize their riding position even more; I am using it with the angle in the fully upright position, but others may need to set the angle differently based on personal preference and body measurements.The BUCKLOS Adjustable Mountain Stem is made of solid aluminum, and it appears to be well made. Everything fits well, and there are no rough edges or other flaws in the product. The hardware that comes with it appears to be high quality, and the stem comes with the Allen keys needed to install it. The only issue I have is not really a fault with the product, but it is something potential buyers might need to know. The part of this extension that goes onto the stem is not as long as the original on my bike, so the original spacers that go on below this are too small, which made it difficult to get the stem assembly back together tightly. I managed for now, and I will order different spacers, but buyers should know that this could be an issue.I really like the BUCKLOS Adjustable Mountain Stem, and it has made a huge difference in the comfort level when I ride. I give it five stars for quality and adjustability, and I highly recommend it for anyone who needs to raise their bike handlebars for a more comfortable ride.
