• Pro: Flange diameter 70mm, hub to centre 21.5mm DS 28mm NDS
    G3: Flange diameter 57mm, hub to centre 17.4mm DS 38mm NDS

    Those were supposed to be the track hub specs, and in the case of the Pro I think the figures are correct. But not for the G3, unless by some mysterious coincidence the hub-to-centre measurements are the same on the road and track hubs. Which seems very, very unlikely.
