I have the Scott Speedster S1. It is a great bike. It really has everything I was looking for. It climbs great, is very responsive and accelerates quickly. The S1 / S10 is the top end of Scott's aluminum line with full 10 speed Ultegra and the CR1 carbon fork. The lower lines don't have the Cr1 fork. Not that it is a ton of miles, but I have put in over 4000 miles on it in about 8 months. Some day I would like a ti or carbon bike (or both ), but for now I'm very happy.
