5, 6, 7 and 8 speed chains
7.1 mm wide 8 speed chain will fit all the other systems (5, 6 and 7 speed ones). Shimano, SRAM and Campagnolo all use the same chain with 8 speeds. Chain for 7 speeds is a bit wider – 7.3 mm, while a 6 speed one is substantially wider – 7.8 mm. That is why the reverse is not the case and a 7 speed chain and especially a 6 speed one will not work as well on an 8 speed system.

Of others, 9 speed chain can work. It is a bit narrower than optimal, but it can be used. Reverse is not wise, since wider 5 – 8 speed chain can get stuck between narrower 9 speed sprockets.

Going further narrower, like a 10, or 11 speed chain on an 8 speed cassette can and often does work. However, especially with older 6 speed cassettes combined with 11, or 12 speed chains, there is a risk of a chain getting stuck between cassette sprocket teeth and/or poorer shifting.
