As always it depends on the bike and hanger geometry so what may work on someone elses bike may not work on your mates and vice versa.
I used a 30t sprocket on my Dura Ace 10-sp equipped Canyon, didn't notice any rattling or touching of gears. his derailleur hanger is the same, as is the geo of the derailleur. trial and error the way to go then? anyone here tried?
