Having a tour on the books is great motivation to get projects off the back burner and make them happen. It has only been a year since I wanted to adjust the gearing on my Sherpa and I finally got around to it! I went from 42/32/22 to 46/36/26. With this setup I'll stay in the 36T chain ring 95% of the time and only shift down to the granny for the steepest hills. With the previous gearing I'd end up having to switch back and forth between the 42T & 32T rings to stay in my normal cruising range.
