what a difference! re-entred my 1987 performance vitesse i got from cyber-cyclery 10 years ago, threw new tires (700x23, punture resist BN, 100psi, road). it hummed both ways today (compaired to mb tank), apples to oranges! had a cop pass me, swing into parking-lot, watch me pass, then pass me again (closer) tonite on the way home (must have been all the lights = 5 total including headlight). i am a roadie by choice!
