I'm looking for a really lightweight bike. I currently have a steel framed bike and it's way too heavy for me. So what's the better/more practical of the two: chromoly or aluminum?
Chromoly hands down. After time aluminum starts to wear down, and break. Aluminum is lighter, but it comes at a disadvantage. I prefer not to buy aluminum things for my bike, if they go under stress for any period of time they are permanently damaged, and break easily.
