PSVs are fantastic, really lightweight bikes, as long as you know how to ride them.
They tend to be a bit whippy, because of the very light gauge SV980 tubing.
If you tend to be a pedal masher, you might get it to ghost shift on you, specially if you pound hard on it on climbs (My 1984 PSV did it really bad after I installed a Campy NR RD on it. Straight parallelogram RDs like the Campy NR, just does not work that well with the PSV.). It's also quite easy to get your chain to rub on the FD cage on steep climbs. But if you are a spinner, it's the perfect bike to fast, long distance motoring on flats.....
