yeah -- l'm not really sure why Marin doesn't just cut them to a sorta normal height --- no doubt they do go through the process of cutting down the fork at the factory but, why leave them still so long? hybrids, XC, road... they're all left with really long steer tubes, and several extra inches worth of spacers.
beats me --
doesn't bother me too much... l never have to buy headset spacers.
