Wow this an amazing reference. I just got mine too, and this helps a lot. Anybody have any info on additional sets of rims? I like to run street and knobbies at different times of the year, and had resigned myself to just popping the tires off and switching them around. Without paying 1k a rim, are there any alternatives that fit? Like a 650 GS rim or anything. Thanks for all the effort with this spreadsheet!
