Steel. Weight indicates chro-mo., just trying to find out if it's a Performance-branded frame (which isn't a bad thing, given the year) or something Performance had powdercoated for some kind of promotion, which is what the seller says...

I tossed some black aero wheels on it with yellow lettering, and it looks pretty good, even to my 14-year old, which is uncommon. I may just sell the 105 group, wheels and all, and build this one.
