they dont have lips.. the steertube is thicker, and they milled the top out a little so the very bottom of the stertube fits into the top of the fork. you cant reinforce them with a t-tube tho :(
dude im getting a new steertube soon. if you just buy a stem, ill ship you my old steertube for free, and you can just buy a crossbar at lowes. my steertube is like 18.5 high.
lol im not starting school right away, and im only taking a few classes, but thanks =]
and depending on certain circumstances, i might be coming to SD.
