dunno-- but nothing to sneeze at. you've probably got a tange headset and these levers... and they're certainly of equal quality for the era. rock them things! loads of bikes from the early/mid 80's had that combo along with 600 or whatever-- if not outright gran compe brakesets. i always liked them- and they'd save you a bundle of scratch for a good drivetrain... they sure whup up on new tektros
