I have a 1999 Trek 2100. It is a 8SPD (26-12) cassette with Rolf Vector wheelset. I have been thinking of bulding a new wheelset for it. At the same time I've been looking at cassettes and hubs. With all the over lap in the gear ratios. I cant see a justifacation in going to a 9 or 10 speed. I have a 105 DR group. So I can use the same DR's. I know I would have to change the STI shifters and chain. With the shifters costing 200-300. I'm beginning to think staying with the 8 speed and putting the money in the wheels. I would like DT Swiss hubs, spokes, and Mavic rims. So my question is whats the benifit from the exspense of a 9/10 speed. It cant be gear ratios because of the over lap. I'm beginning to think it was a marketing thing for the bike companys. Cause a 52/12 gear ratio is the same weither its a 8 or 10 speed cassette. Just more over laping ratios on the 10 speed.

I have a Campy 8,9 and 10 speed bikes. The 8 speed Chorus, which was just replaced by a 10 speed Daytona, was much less fussy than the other bikes. The only real advantage is the gears are spaced tighter. Those who spent the money will try to justify their purchase. After riding my new 10 speed Daytona I can say it performs no better than the old 8 speed. It is still very nice though. I upgraded because 8 speed Campy derailleurs are getting scarce and very expensive even in beat up condition. Good luck

The shifters are nicer. My impression is that the fewer speeds there are, the longer most parts last. That's prob not entirely true, but Sis has been using the same 7 speed bike with nothing but tuneups for what feels like a million years.

I am currently upgrading Wifey to 9 from 8 because the Grip shifters hurt her wrists. It's been more expensive than I thought it was going to be.
