Park Tool Folding Chain Tool with Peening Anvil CT 6.3

Now 11 speed compatible, the CT 6.3 removes and installs chain pins in all derailleur chains. Smooth and powerful, this handy take along is encased in a stainless steel shell, which becomes a comfortable handle when opened. Also included is a peening anvil that allows for peening of CampagnoloR 11 speed chains, which pivots out of the way when not in use.
