hi all, i ride a peugeot road frame that i converted into a fixed gear over a year ago. i ride it every day and love it, everything feels great. now i'm planning on buying a frame that is actually pretty nice (a debernardi thron track) and seeing as i'm laying out quite a lot of cash (at least for me) i want to make sure the sizing is right. there aren't any shops around me that carry the bike so i'm going to get it online. anyway i'm just curious about the sizing. when i measured my current frame it came out as 55 cm (CC) seat tube and 56 top tube. that seems to correspond nicely with debernardi's 55 which has the same two dimensions. so do you reckon i should go ahead with that frame or is there something specific to the geometry of this bike (or track frames in general) that should make me opt for the 53 (which is what various sizing charts, and other threads seem to indicate. i'm 5'9 and have a 31-32 inseam. keep in mind this bike will be used almost entirely on the road, i'm not a racer, but don't want to be riding a boat.

thanks
