awhile ago, i bought a bike for a couple bucks at a garage sale. i finally took it apart tonight to figure out what's wrong with it, and my final conclusion is that it needs a new headset. but there's an ACS rotor on the bike, and if at all possible, i'd like to keep it. but is there a newer headset that's going to be compatable with this rotor, or am i going to do some more hunting to find an older headset?
if anyone knew what kind of headset (specifically) would work with an ACS rotor, that'd be awesome.
