'Luminum or steel headset?
 

One of my bikes needs a new threadless headset. Am I missing the boat here, or shouldn't a headset have steel bearing races and cups? I think I want steel for durability, but almost all of the threadless are made of aluminum.

What gives? Is it just weight issues, or is aluminum a better metal for headsets?

If It uses a cartridge bearing(as in most current new designs),the bearings don't run directly on the aluminum cup anyway.

Got it, Thanks! for explaining that, Sydney!
