My wife had a problem with the handlebars too far forward on her Lectric 3.0 E bike. we weren’t sure these were going to fit, but they worked perfectly. Pretty easy to install, great quality, handlebar is now adjusted.

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.

If fit perfect, and it brought my handlebars a little higher and a little closer to my body, which is perfect. Luckily, it comes with two thin spacers that were definitely needed to tighten the neck up with the bearings.

Moved my bars up and back toward me about 3" once adjusted. Really saving my back sitting more upright and I get to see a lot more without straining my neck to tip my head up to see. Totally changed the feeling riding on my bike that before had a fixed neck and clamp. Holds position perfectly on my mountain bike. No worries.

Fast shipping and great product. Be careful ordering though, it’s kind of confusing on the sizes. Took me 2 times to order correctly. But, well worth it.
