You're talking about your Koga, right? Funny thing is, I've got DA 7710 chainset with a 53t ring on my Full Pro track. Mine's later year though (white instead of nemo).
How much clearance have you got? Was your chainstay crimped?
Not crimped, tube profile might be a bit squared at that point. I checked the clearance and it's just a little over 1mm.
