This has probably been covered before, but I have no luck with this site's search function.

A vendor advertises the 9-spd. Shimano chains as being compatible with 8-spd. system as well. True? If so, will they work as well as a wider 8-spd. chain?

Specifically, will a HG-72 work on a '96 105 group?

Thanks

Shimano 7/8 speed chains are 7.4mm wide. Shimnao 9-speed is 6.6mm. SRAM chains are 7.1 and 6.9 respectively. Bottom line: buy the correct chain for your system.
