I have an 80's Japanese bike and it has the smaller tubing. I wanted to update my options for modern handlebar stems and handlebars. This adapter stem is perfect. Easy to install and attach the newer stem and handlebar.

Nice stem adapter. Good color. It goes well with my bike. Stem is compatible with the handle bar stem I'm using and works well.
