Works as advertised and fairly easy to install.

The stem riser raised the handle bars up enough so I didn't have to lean over as much which made it more comfortable to ride.

Now I have a more confortable riding position and the bike is still much faster than those "confort" or "hybrid" bikes.

I'm 6'3" and my seat has to be pretty high to let my legs extend in the right range. Problem is, I'm then hunched over like a racer on the handlebars, and my hands/wrists start aching because of the constant pressure. I'm over 40 now, and I prefer a more upright style. This extension is perfect for that. It puts the handlebars a few inches above the seat. Fortunately it also matched my alloy handlebars and original stem.

Installation was a snap. Exactly what I needed.

This product was easy to use and install. Just be sure to have a very long extension for a click stop torque wrench to get the hex bit all the way down the shaft to tighten the nut to hold the quill inside the bike frame.

Works perfectly. You need to use it with an old-style headset, though. Won't work with aheadset types of headset (clamp on).

I'm tall and so I needed to raise the handlebars up on a 22 inch frame. I called all the local bike shops and none of them had stem risers so I took a chance here despite a bad review. I very glad I did because this product does exactly what is is suppose to do.
A word of caution for those less mechanically inclined: I did have to remove all the breaks and all the hardware from my handlebars then put back on when finished - it took about an hour.

I ordered this item so I could raise the handlebars on my vintage Trek 510 to a more comfortable height.

Other reviewers mentioned that it is difficult to sufficiently tighten the stem extension. They are correct.

My order arrived on 9/11/13 and I anxiously installed it when I got home from work. Tightened the extension's bolt as tightly as I could, re-installed the handlebars and headed out of the garage for a test ride.

I had just put my feet into the toe clips and was coasting slowly when the handlebars suddenly pivoted 90 degrees. Instead of the handlebars being at a right angle to the front tire, the bars and the front tire were parallel to one another. This is not a good situation! As my body impacted the concrete driveway, I knew from experience that I had fractured a couple of ribs. Actually, three of them plus had collapsed a lung.

Since being released from the hospital, I have tried numerous times, without success, to tighten the stem extension. I've confirmed that it is the correct size.

This item obviously worked for some folks, but for others it is a disaster waiting to happen. If you install this, be sure that it is tight before taking a test ride. Chest tubes are not fun!

Delivered on-time and worked fine. I think this is a good buy for the money. In my case, I only had to replace the front brake cable.

I found that riding on my bike all bent forward for any period of time hurt my shoulders, so I installed this stem riser, which gave me a more upright seating position that greatly improved my riding comport.
