Given that my chainrings no longer have the chain guards, I have to make sure the chains are wrapping the large chainring properly.
I never go big-big or say cross chaining so the rear forking rubbing is never a problem to me.
I'm not so sure about 58T though.
Thanks for this information. I was thinking of resurrecting that project when I have time and inclination. One of the problems I previously encountered was the likely need to dismantle the cranks and to the chainrings out so that the front derailleur would work properly.
