Re super compact chainset; isn't there a problem anyway with derailleur hitting the chain stays? I'm on 48/32 on the Stayer and it's well close, not sure I could go much lower.
48/32 might work but I'd have preferred 46/30, the derailleur is at the very bottom of braze on tab and yet maybe a millimetre out than what shimano recommends.
