This small chain tool goes anywhere and actually performs like a shop quality tool. The fine thread, special Vshaped handle, and super strong replaceable pin make chain removal and installation a breeze. The CT5 works on any derailleur chain including Hyperglider and has a shelf for loosening tight links. At only 77 grams, it is the perfect takealong chain tool. Works great on 9 and 10speed chains as well.
