Hi I wonder if anyone can help,I am fixing up a old postmans bike for my son but the bike has no chain.i am trying to source a chain for it as it is not a standard size chain, the cogs are slightly bigger. I have been to a few bike shops and they do not seem to know where to get one from (apart from India). Surely there is somewhere more local. I know I will have to pay a premium for such a chain but getting one is the problem.I am in the uk so any one with any suggestions would be most appreciated. Thanks
