Hi All

Im new to road riding after a few years mtbing. I am looking to get my first 'proper' road bike since i was a young boy. I must have caught the bug after watching alot of the TdF and now Olympics and plan on going to Stoke for the ToB in september.

Please can anyone suggest what is suitable?
Im looking at some at the moment such as Specialized Riboux type or Giant SCR Carbon type, Colnago Arte/primervero type.

I want a half decent group set after being used to XT/XTR on the mtbs.

Also, im a little confused as to sizing - im about 5' 5" with inside leg of 28" and used to ride small mtb frames.

many thanks
chris
