Yeh man, it sux to be a midget.Really? I'm a touch under 6'1" and I ride a medium SXT.
EDIT: Hey shorty, just came to think of Devinci Hectik and Frantik, they're almost identical bikes to the SXT's and both come in XS!

Nice and slack for DH but with a little higher BB than some (which is to an advantage for my short legs).
