Folks, I can't take credit for discovering this site. It was posted by someone else this week in a thread and I happened to visit it. Maybe it's only new to me, I don't know, but if you have ANY questions about ANY of the most popular tri bikes, this is THE most informative site I have ever seen. There is also a superb article, among many other features, on wetsuits. Bookmark this one. http://www.bikesportmichigan.com/
