KMC X10 10 Speed Chain
KMC chains can be used as a replacement for Shimano, SRAM and Campy chains. They are known to be fairly quiet and have a smooth shifting response. Conveniently, they are non-directional so it doesn't matter which direction you mount it. Rumours also suggest that they are known for getting pretty decent mileage.
This KMC X10 chain is for 10 speed drive trains. They have 116 links and include the well regarded KMC missing link, for when you want to take your chain off for cleaning or some exciting laps.
