From what I've been told magnesium could save me over an additional pound on each wheel. So naturally that would be my preference. My fear is that magnesium could also be a one way ticket to divorce court. Out of curiosity I would like to know the cost of magnesium, but from a practicle point I need to consider aluminum. Again, if I should be looking at something else, I'm open to suggestions. Pretty has little or no influenence on me, the lighter the better. I'm a canyon rider with a 56-3/8" wheelbase, the odds are sooner or later I'm going down. The last thing I'd worry about is scratching anything, much less a wheel. Mike
