• Nice looking Argos frame. Have you any idea what type of tubing it is? Is the mixed tubing 653? I wondered if the steerer had a stamp of the tubing type.

    I haven't had the forks out since I repacked the headset last year, I believe it was fairly common practice at the time (especially at Argos) for the builder to spec tubes from different sets for different areas of the frame (to achieve the dreaded 'lateral stiffness / vertical compliance' in competitive racing frames) hence the absence of a tubeset sticker. If you're interested in the frame I could remove the forks and check for a stamp on the steerer?
