I have had a look 585 since March06, have about 5 k miles on it, longest ride just over 100m twice, very happy with it, it is stiff and responsive, yet comfortable. Also very light, climbs very well. I rode the first leg of the triple bypass in colorado in july before wimping out because of the rain, first leg if you are not familiar is a 16 mile climb of about 4000 feet, my time on the 585 was about 12 minutes faster than last year(on a trek 5200)-obviously that is not all the bike. I had a frame issue which look handled well, the bottom bracket shell separated from the frame, they warrenteed it, sent a new frame, took less than two weeks for the whole thing. I love mine, would not hesitate to get it again. Three little words that say it all "five, eighty, five".
