    Fellow Cyclists,

    I had a professional fitting done to in anticipation of ordering a
    custom geometry bike. With the fitting I found out that I had a short
    torso and arms which requires a geometry with a high front end and
    relatively shorter top tube. The fitting was done on a Serotta Size
    Cycle but the frame was done by another manufacturer.

    The frame builder addressed these issues with a longer seat tube and a
    slightly sloping (up) top tube and a taller head tube. Unfortunately
    in dealing with these issues it appears that the stand over height was
    missed by about 3/4" i.e. the bike is about 3/4" higher than was
    recommended by the fitting.

    wadamiinute!! Custom frame and one of the dimensions was
    'missed'...they need to make ytou a new frame-easy!!

    So far I have had a test fitting on the new bike but haven't been able
    to ride it since the seat post provided was too long (won't go low
    enough). I can just barely straddle the bar with bike shoes on. I
    would estimate that there is currently somewhere 0-1/4" clearance if I
    stand just right. The bike currently has 23mm tires on it but I will
    probably switch to 25mm when these wear out to reduce the chance for
    flats. This will only make the stand over height worse.

    Is this stand over height likely to be an issue? At what point would
    you consider stand over height to be insufficient?

    Thanks,

    Steve

    That could well be the case - or maybe not...

    The first question is how do the OP and the builder define "standover
    height"? I've seen some manufacturers measure it at the top of the
    top tube where it intersects the seat tube (makes no sense, other than
    to produce an artificially low number). Most others will measure this
    at the top of the top tube at the mid-span of the top tube. Maybe
    there was a disconnect there?

    Also, I know I've gotten "impossible" combinations of specs from
    customers before... for example, they might ask for a head tube with a
    certain length, a head tube of a certain length, and a standover
    height of a certain height - but when drawn out, the line from the
    lowest possible head tube/top tube junction to the requested seat tube
    height will miss the standover height requirement by a LOT. Then it's
    always a question of which the customer would prefer to compromise on.

    The other point is that the builder should have provided a drawing of
    the frame to the OP before the frame was built. Perhaps this drawing
    listed the SO height - maybe it didn't (mine always do).

    So... maybe the builder screwed up, but it's also possible the OP
    misunderstood something, or perhaps there was just a mutual
    misunderstanding about something.
