I've dealt with designing and fabricating parts out of aluminum for most of my professional life, and in the past 25+ years for aero- and outer space programs and let me tell you, there are aluminum alloys available that can match the strength and come close to the thermal expansion of good steel.

I just bought a new used track bike frame, my first aluminium frame. It's the stiffest freaking frame I've ever ridden. When I stand up, there is ~no~ flex in the bottom bracket area at all. Not compared to what I've been used to in riding steel all my life. This has nothing to do with

Well, in Canada (being a Canadian and all), I've always seen it as aluminium. It may be changing, as we are constantly being inundated with US culture and customs. But when I was a kid at least we spelled it the British way, and pronounced it the American way (if that makes sense) g -frank
