Good to know. Nice setup. I called Nashbar last week and I was told that they were expecting the racks the previous week. So maybe I'll have it in a couple weeks.
I already ordered some radius-type washers for the front/rear. I plan on using two racks. I've seen one mounted on the rear of a 29er and looked good with clearance. Photo(s) soon.
I also plan on making my own bike bags (no panniers).
