During my travels on the net .Looking for the bike . I have discovered a big change in sizing .I have a 64cm Dawes Galaxy.The seat post is not overly high .But i do have a mountain bike stem on the front .To bring me into a upright position . Well today i was checking The 61cm Spesh Secteur Elite against the largest bike ,which to me was a 64cm Trek 2.3. About £1200. The spesh costs £999.99. And do you know the spesh is a longer bike .Wheelbase being 1038 as against 1018 on the Trek. The top tube is about one finger width longer on the Trek . So 64cm is not always a sign to a bigger bike .
