Dragonfly Chain Tool

This chain tool can break and install 9-11 speed chains with ease. The true genius of the tool is built in port snapping off guide pins and the 11-speed Campagnolo peening gate that's just a finger flick away.

• Replaceable rivet pin 
• Interchangeable chain gates for 9-10 speed or 11-speed with peening switch
