It is important to keep your headset clean and tight. The original Cannondale “Ernie” tool is used to easily remove and install the XC3 stem/steer tube unit without damaging anything. After removing the XC3, the Lefty comes right off of the frame. If you’ve ever tried to do this without this tool, you’ve probably squished your upper bearing seal and scratched up some of the other surfaces inside. Make your life easier next time with the KT020.
Machined from heavy, quality plastic, this is a shop quality tool to be used over and over.
