Oh i have formulated myself pretty bad it's the chainring I'm interested in, in the two pictures

As for the drivetrain I have a Phil BB (113mm'ish, was on my frame when i got it so I'm not 100% sure of the size. EDIT: I'm 90% sure it's a BRS10S "68mm - Campagnolo Specific 110.5mm") and a Phil 120mm fixed/fixed rear hub. Just so you know what the crankset and chainring has to coop with

My only worries are that i make the same mistake again as i did with my RD2. A perfect chainline is priority no.1.
