I raced a 59cm 979 one year in the late 80's when I weighed about 170lbs. I remember winning over $100 in a points race in Salem MA, so I guess it worked okay. Not one of my favorites, though. It seemed both flexy and dead (no zing) at the same time as I remember. I don't recall what tires I used.........
