The PC-1091 chain offers more heavily chamfered outer plates for improved shifting and quieter running. Other advancements include an inner plate finish plus chrome hardened pin construction, both for longer chain life.
The CT-6.3 removes and installs chain pins in all derailleur chains, 5 to 12-speed. 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.
