I have built-up an old, 90s steel MTB frame with original and spare parts. For simplicity (and because the original Alivio one-piece chainset was shot), I have added a single ring up-front. The problem I have is the chain slipping and also coming off the chainring.
I have tried 2 different 7-speed cassettes, the chain is new (and correct length), and the rear mech has no play in it. Does anyone have any ideas what the issue could be?
Thanks
