I own a 2009 Specialized Roubaix Comp (52cm), upgraded with Campy Chorus 11 speed, Rolf Prima Elan wheels, FSA Kwing carbon bar, Pro3Race tyres. I absolutely love the Roubaix, but 90% of my weekend rides are around 55-65 miles and my week rides are 20mile fast group rides.

I’m itching to try a new frame with a little more bite. The Specialized Tarmac Pro is the frame I want (Tarmac SL2/SL3 is my dream frame), but before I drop the $, I need some advice on sizing, pls:

I got a professional fitting and in order to get comfy on the 52cm Roubaix:

- I use short reach bars and 70mm stem – pretty much the minimum reach you can achieve on this bike
- I have dropped my bars all but one spacer (the Roubaix has a tall head tube – and I like a nice drop from saddle to bars, probably 3 inches right now)
- My seat is slightly forward of center, but not loads, I’m nicely over the pedal axis
- When I got fitting, the guy said I could maybe take a smaller frame

I don’t want to buy a new 52cm Tarmac Pro 2010 frame and have to bang a 70mm stem on there. Seems to be an indicator that the frame is a little off for me. I am 5ft7.5 and 72kgs. I have normal proportions, but a littlee longer legs and shorter arms. I don’t know how to properly measure reach, but feels like I need a top tube length of 525mm (49 tarmac = 518 and 52 tarmac = 537). I also saw the 49cm Tarmac in my LBS and it looks like a child’s bike and the 700 wheels seem giant. (Although Paulo Bettini rode a 49cm SL2 for two seasons!).

Any advice on getting the 49cm or 52cm Tarmac Pro? Or another awesome frame such as LOOK?

    For that kind of money I'd want them to get the frame in and stick stem/bars/wheels on it (and preferably a chainset) to try first
