Contec: Club, for Shimano 7-/8-/9-/10-speed, IG/UG/HG-chains, incl. spare pin. The chain breaker opens and closes the chain completely without the use of a master link. The replacement of chain links is thus particularly easy.
Topeak: An excellent value in a basic do-it-all chain tool. This 2-piece cast CrMo chain tool features a hollow removable handle which can be slipped over a small Allen wrench to provide extra leverage. The Universal Chain Tool includes a chain hook to make chain repair easier, is compatible with all single speed and most multi-speed chains, including 10 speed hollow pin chain. (Not compatible with 11 speed chains.)
