I bought exactly the bike you have pictured back in July. I have put over 500 miles on it in less than 5 weeks. I have found it to be very comfortable up to about an hour. After that, my rear starts to hurt a bit. My longest ride on it has been about 35 miles. The bike is very well made and very smooth. It shifts effortlessly.

I have been riding more than I ever thought that I would, so I ended up buying a felt f65 for my daily rides, but I am using the sirrus as a commuter and to ride with my wife on the weekends.
