Park Tool Ct-6.3 Folding Chain Tool With Peening Anvil

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 Campagnolo 11-speed chains, which pivots out of the way when not in use.
