I don't know about the adjustable travel for the '01 and '02, but the '03 has it (I'm sure someone else can chime in). Also, the '02 did not have a replaceable rear derailleur hanger and the '03 did. IIRC, the '03 has a one-point-five headset while the '02 has the 1 1/8".
Stop jockin' your homie and get the Santa Cruz. Just kidding.
