You need this tap kit if you want to install OneUp's EDC tool using their original Threaded top cap method.
Used once. No longer needed as I don't have that bike anymore and sold the EDC with it.
The OneUp EDC Tap Kit includes: A Star Nut Puller / "Go No-Go" Gauge,Tap and Tap Guide. (A Tap is a common cutting tool used to manufacture/cut internal threads)
