Thanks for the help. I did go to the Specialized site and looked at the bike sizing. And yes it is a road bike with slightly fatter road tires and a straight handle bars. I used to ride a Bennoto road bike that fit but no longer have it and I don't rememberr the size. I want to sit up straighter and relieve the neck ache of riding in the drops all day. I'm not trying to ride centuries any more. Those days are long gone. I'm considering the Sierrus with the aluminum frame. Although I've never owned a bike with an aluminum frame, I remember others that had the Cannondales and complained about the stiff frame. My old Crom moly frame had some flex.
