I reviewed this purchase already. It was rejected. It was positive. I'll do it again. It looks nice. Easy to install. It's more comfortable riding. It looks durable. This was a better value than replacing handlebars.

This bike stem extender was the perfect fit and function to raise and angle my handlebars for a more comfortable ride.

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.
