Easy install to raise handlebars.
This product was easy to install, and raised my handlebars to a height where I’m not leaning forward so far. Takes the pressure off my hands. Makes riding my new bike much more enjoyable, especially on longer rides. It is solidly built and blends in perfectly with my bike. You wouldn’t even know it’s there by looking at it. If your sick of the constant lean forward and numb hands, give this a try. Highly recommend.

A simple fix for a major problem
I was skeptical about if this would be both effective and durable. Check both boxes. Installed it and it raised my handlebars on my new-to-me Specialized mountain bike. I bought the bike used and it was so uncomfortable to ride do to the low bars in relation to my rear. It was so bad I wouldnt ride the bike. The extender was simple to install and now my body is aligned correctly when i am riding the bike. I rode it 14 miles today and it was just as comfortable at 14 miles as it was at 1 mile. This extender is also very heavy duty and the handlebars are rock solid with the extender.

Great product even with no installation instructions provided
Dropped the score because the there were no installation instructions provided. Just packaged in a box. Having installed one of these before it was straightforward. However if someone had not, then some additional research would be required.Otherwise works great. Appears strong, holds and should work well.

Perfect Stem Riser Extension for the Mongoose Ardor X1
I have a Mongoose Ardor X1 mountain bike with 27.5″ wheels. I put a larger saddle on the bike and I have to raise it a few inches to get the proper clearance to the pedals. The handlebars on the bike were too low to be comfortable. I got the Zukka extension because it had good reviews and a great price. The Zukka is perfect!!! I raises the handlebar about 3″. I took a test ride and it was like being on a new bike that was made for me. The Zukka also has screws that line up with the screws on the handlebar keeper so it was very easy to line up with the fork and the wheel.

Sturdy Build, Easy Install!
Impressed with the quality of this component! Fit and finish are on par with options 4x the price. Installed in 5 minutes and all necessary hardware is included. Reuse your own top cap or use the one provided. This will absolutely improve the comfort of the tandem bike I installed it on! No more hunching over.
