I found some more info on mtbr.com, enough that I slapped on a new set of Stans 650b rims. I have only had the chance to ride about 7 miles on a mild extremely leaf covered trail, but I loved the way that they felt. I currently have it in the xc setting(always have) and did not experience any rubbing at all, they have plenty of clearance. I do have another rear shock on the way and at that time I may try the fr setting. Loving it so far but it is still early in testing process, need to get some more miles in.
