I have a Pilot 5.0. I got mine about 3 months ago to replace a year old Trek 1200. I'm 37 and in pretty good shape, but the 1200 really beat me up after 50 miles. We're riding a century next weekend and we've been training for it for a couple months. Last two weekends I've ridden 78 miles each day and have had no problems. Very comfortable. The only problem is finding a good seat. The one that comes on it is nice and soft and only good for about 25 miles and then it gets very uncomfortable. I now have a E3 form and it's not bad. I may look at a Brooks. I would recommend it. It's great for long rides, but maybe not the fastest as the aerodynamics aren't as good as your regular roadie. But after 100 miles, I think I'll be glad to give up the speed for the lack of an aching back...
