• I’am assuming frame builders have put bottom bracket in same place as a conventional 700c 57/58 as looking at main photo there isn’t much of a drop down in a line between hubs ,I remember in building her taking all my measurements off the bottom bracket,saddle and bar/stem position was same as my 700c Serotta

  • Ahh right I see. My bad.

    Whatever was the point in 650c then other than for a better proportioned bike for smaller riders?
