back in business. the stem is too short, and i want to put b-123aa's back on there, as well as get a new saddle and seatpost, but it will do for now.
huge thanks to all who offered parts and/or sympathy, you guys rock.
(mike, i didn't use your seatpost, so i'll get that back to you next time i see you, or i can drop it off somewhere if you like).
