found a link to this guy on the lfgss-forum. he has done a couple of really long tours on his fixed gear. see what he has to say about fixed gear touring after a couple of thousand miles.

"The fixed wheeler was a mistake this time. I was under-geared for a long time in the two flat countries and by the time the REAL mountains arrived I was exhausted. That's absolutely the last time I will ever tour on a fixed wheel. I've done 10,000 miles loaded fixed wheel touring since January 2005 and I can confirm what you've all been telling me. It's a real pain - in mountains, on rough tracks, on the very flat and when you are ill. Never again!!!!"
