Same frame size - both bikes fit me with the same length stem and a similar amount of exposed seat post.. I haven't measured, but the wheelbases are probably pretty close. These are both race bikes with tight rear ends. I think the aluminum bike has a slightly slacker head tube angle, but probably by less than a degree. The most noticeable difference I feel between the two is in lateral stiffness under heavy power, but there is also some difference in the smoothness of the ride.
