The ultimate. Along with superior strength
and durability, the CT-3.2 features a handy "loosening
shelf" to remedy stiff links after reassembly. The fine
thread and comfortable size enable easy removal of even
the toughest chain pins. Like all Park Tool Chain Tools, it's
easy to use and built to last.
NOTE: The "sliding shelf" is supposed to be free floating. Do not try to tighten it!"
Works great on 5 to 11 speed (not Campy 11) chains.
