FWIW-- That is an awful lot of weight. Granted you may have used everything, but did you need it? My wife and I did an 11 week fully loaded-- She had 30 lbs and I had 40lbs. We ended up sending some of that home, so we ended up even lighter. The point being you may be able to go a little more "spartan" and find it a lot easier on you and the bike. We come from a mountaineering background so packing light has never been an issue. I'm surprised that you have not had any wheel problems. Good luck on the remainder of your adventure. My advice-- take any advice with a grain of salt
