I filed a couple of notches to correct that issue, but the rack still tends to slide down under load (and rubs the top of the tire). I wouldn't recommend this rack for much more than light commuting. I would be willing to bet the tubus rack is worth the extra $$$.
You probably would have been better off with the Streamliner DLX that doesn't use any plates since the R600 has two threaded holes in the drop out (at least mine did). I used that rack with two p-clamps on the top attachments on my Cannondale R600. It is very solid that way. I like this rack very well. Some may not like that it is narrow, but I find that to be a plus.
