I've done six days on my Cross-Check (with an internally geared hub), and it worked great. I'm leaving for a few weeks to Michigan's UP around May 5th and have no worries about it. Note: its fork doesn't have mount points for a front rack. I get by just fine, however, with just rear panniers and a handlebar bag, but I don't do any cooking on tour (I do camp each night, though).
