As I said before during test trial I felt uncomfortable about reach/top tube lenght but calculation says opposed. It may related about my inexperience on road bikes, maybe it's normal to feel like uncomfortable at the beginning.
Stack 531 - 547
Reach 380 - 390
Effective Seat Tube 510 - 540
Effective Top Tube 537 - 552
Head Tube Lenght 130 - 145
Wheelbase 977 - 987
I'm not saying the Competitive Cyclist calculator gave you bad info, but I'm going to give you a real world data point to consider: me (as stated above 173cm tall, 76.5cm inseam). I've been riding bikes for a long time. I know exactly what works for me, and I can tell you that my dimensions work best on their S, with a 110m stem. I can ride the M, but its stand-over is higher than I like. Think about that. You and I are roughly equivalent in height and inseam. For all intents and purposes you and I ride the same size bike (macro adjustment), that is where the fitting comes in, to dial the micro adjustments at the contact points with the bike: bars and saddle position, along with cleat position on shoes.
