• Stack and reach measurements are your friend. Do you have a road bike that fits?

    Unhelpfully my only bike is commuter/do it all a flat bar Pompetamine, in medium, with a 130mm ~+10 degree stem with about 15mm of spacer under the stem. I can obviously measure/try and work out the stack and reach for this but not sure how helpful that would be given the different purposes I intend?

    Using http://bb2stem.blogspot.co.uk/ for the pompetamine (from the on one geometry chart) and guessing a BB drop of 60mm (anyone know this?) gives
    STACK 518.33
    REACH 372.58
    STACK WITH SPACERS 551.80
    REACH WITH SPACERS 362.35
    STACK WITH SPACERS + STEM 610.82
    REACH WITH SPACERS + STEM 478.18

    I can see that the 56cm caadx has a stack of 587 and a reach of 390, doesn't appear anywhere has the info on the Genesis fork, so I don't think I can easily compare.
