yeah just measured, my old full suss frame (medium) is 585mm TT (right between small and medium gaupo). my old seat tube is only 400mm (less than a small Guapo! Trek “virtual” sizing there) and 440 on my hardtail, wouldn’t want any bigger.
i’m measuring TT horizontal, from centre of steerer to centre of seat tube line.
ST from centre of BB along tube to top. anyone with a guapo around to confirm how they measure please?
not sure, can’t ring On-one as will have expired by Monday.. bugger. erm. i’m leaning towards small as easier to chuck around, but may bash knees? small doesn’t have that bracing tube to top of ST, i’d prefer medium with that.
if you’re 6 foot and i’m 5 10, medium should be fine.. but this years is 10mm longer (in all sizes i think), you have older one? gah. difficult.
btw does EG frame have bottle mounts on down tube?
