I have a Super V 2000 that I put narrower slick tires on - I think they're 1.95s. The bike rides amazing with these tires. I've developed a problem with my hands and was going to do some converting - butterfly bars, rapid fire shifters - but then found a F1000 at a garage sale which had already been converted. I picked it up for $75.00. I'm glad I didn't change out my Super V - the bike is brand new condition and if I do sell it I'll get a lot more than I paid for it.
