Is $400 to get a 4 hour tri bike fit worth it? I have a 70.3 in June and 140.6 later this year, and I want to compete (at least with myself), so I don't want to be on a bike holding me back and I'm afraid my current size is. But don't want to spend that much if it's possible to figure all out on your own
