I tried both of them. The Cannondale felt smaller and slower. It came with Kendall tires which even though the same size as the Sirrus tires, seemed
to have a bigger profile. I went back and rode the Cannondale twice, but I bought the Sirrus. It just plain felt good. Ten months later it still feels great.
When I went for a second look at the Sirrus, I went for a ride. As soon as it started rolling, my mind was made up.
