The lowest model Cannondale Road Warrior has what looks very much like a mountain frame. I have a RW 400 from last year (this year they have new models) and it's quite nice. I replaced an Adventure 600 that I thought was too cushy (Headshok fork, etc., big wide saddle) and upright, The Road Warrior is a nice compromise and I got a good deal on it.
Wanted to look at the Dew but the nearest Kona dealer is more than 100 miles away.
