Hey, if I could afford the top of the line stuff, I would certainly get it. I am on a budget and wanted something better than the stock wheels that came on my 2007 Scott Speedster S30. I read a good review on Bikeradar.com. I will eventually get the Ksyrium SL, but I am going to wait until I can get them with a new carbon bike purchase. I really like the Masi Evoluzione or the the Scott CR1. But that is a whole different topic. For the price, I think I got a good set of training wheels. And perhaps they will help speed up and make my occational commute to work a little easier.
