    2 bikes - effects of relative fork/headtube lengths

    Given the bikes in the image below have practically identical geometries other than fork/head tube lengths what differences in their rides would you expect?

    I can't help but think they should ride differently but can't see why/how.

    I would suspect the bikes would feel very much the same with identical builds and materials. The variation in the offset makes only a slight difference to the trail, and could be nullified by using a slightly fatter/thinner tyre.

    You'd have to be as sensitive as the Princess and the Pea to notice a 1mm difference in wheelbase.

    All else is equal.

    I would expect there may be a noticeable difference in feel though because the longer front fork would have more fore and aft flex.

    A little more fork flex (could be good, could be bad). Otherwise no noticeable difference.

    More flex would be good so that works for me. Cheers both, was hoping that would be the case.
