By the time I got to england, both my big ring and middle ring were stripped, and if I used my little cog in back my cassette would fall apart, and I'd have to try to put it together with a 2mm and 2.5mm allen jammed into the lockring. It sucked and messed up my hands. I was burned out, cold and all I could do was spin. I just didn't want to deal with it. I didn't want to drop bank on a new drive train, when I have new XTR replacements at home, and my trip was almost over. I'ze burnt out. Plus I had three weeks 'til I flew out of Amsterdam, no hurry.
