Lives in a hole
Dickie's right on the mark with the ride qualities of steel, I miss my old steel xc frame :cry: .
Just to clarify for the newbies though (I know I got confused when I was talking bikes to metallurgists when I first started):
Aluminium IS NOT stiffer than steel, in fact, aluminium is a very soft metal. It is however much less dense than steel, so is lighter (and weaker) by volume. So to create a frame of similar strength using aluminium instead of steel you have to use larger diameter tubing. As stiffness increases proportionally to diameter and gauge, using fatter tubes makes the frame stiffer.
So in short, it is the fatter tubes, not the nature of the material itself which makes aluminium frames stiffer.
Hope that helps clear up the issue.
