d'oh, sucks pushing that far
Sorry I just thought of this, but I heard of a trick years ago for an emergency flat. What you do is get one tire bead off, and stuff it full of grass or leaves or whatever's handy. Stuff it enough so the beads will at least stay on long enough for you to limp home. Even slow pedaling is better than pushing, eh?
Been working on a unique fix for dual broken rear studs(came that way, bought it cheap), pics/thread soon.
