    Seatpost diameter of two C-50s
    What is the seatpost diameter of the following two frames:

    1. 2003 C-50 (non-integrated headset)
    2. 2010 C-50 (integrated headseat)

    I believe the early C-50 had a 27.3 mm diameter and I think the later model had a 31.7 mm. Can anybody confirm?

    There is no C-50 with Integrated Headset

    The first Colnago model with integrated headset was the EPS

    All C-50s and also C-40s have a 28mm Seatpost diameter.

    The EPS had 31.6

    Masters and others steel models have 27.3
