oval chainring help required
Whilst dumpster diving I came across a biked covered with spilt paint, no wheels but all the remaining running gear. aside from the paint spillage it was in exceptional condition.
Whilst dismantling the chain ring to clean off the paint I realised the cogs were oval.
Silly me, I didnt notice beforehand so now I have no idea where the long axis of the oval should be in relation to the cranks.
