@Julio
I set up my boyfriend's bike for him (he must be desperate if he's letting me do it!)
and there seems to be a problem...
We bought a 1/8 rear cog and a 1/8 chain but we're using an old bianchi chainring that's been kicking around our flat. Not sure where it came from.
Anyway, the chain's all oiled up and he went out for his first ride on the new set up this morning... but the chain is really noisy, almost as if it's the wrong size or something.
So here's the question: how can I tell if the Bianchi chainring is compatible?
Or could it be something else, like maybe the chain line is out? or it's too slack?
Thanks for any help!
