Hi Guy's, I've read about chain widths before but now the more I think about this problem I have the more I'm confused!
I got a little 24" wheeld mountain bike given for my son which had 6 speed grip shifts on that he couldn't get along with. I fitted a 7 speed block and some 7 speed rapid fires I had kicking about but it seems that the chain is rubbing the block in the higher gears causing it to jump however I thought 6 and 7 speed chains were the same width. Is this right or is it that a 7 speed chain is compatible with a 6 speed block and not the other way around?
