maybe a silly one, but as in keeping with the retro bike feel, how likely is it to get hold of a retro chain, is this something most people don't fuss over and just to buy a good modern chain is important, as i want to ride this retro mtb a lot. I'm going to be running a 7 speed shimano cassett, with deore XT rear and front mechs, and a Deore Crank. Is it possible to get a retro deore chain or is this very unlikely, or am i being an idiot!
