I needed a new chain for a beater I'm putting together for a friend. The only chain I could get hold of - need it for tomorrow, is a cheap end SRAM chain. It says it's for 6-8 speed - this bike's a 7 speed, only it's Shimano Dura. I've not opened the packet yet, so I can always return the chain. ANyone know if it will be okay with the Shimano gearing, or are they incompatible?
Oh I should explain, it was from Decathlon, and the spotty teenager on the bike counter didn;t know.
