Hi! I just wanted to thank everyone who followed my last post. The information really helped. Too many bikes were in discussion on my last post so i started a new one. I just wanted to tell you that our final bike choice was the trek 3500 with a 19.5 inch frame in the onyx color. I originally thought i was going to get my son the trek 820, but the local bike shop gave me a good deal on this better bike. I will post my sons experience with the bike after we get it! Thanks again, and we really love this trek 3500!
