I have a 2000 cannondale R800 (this bike is awesome) and I was recently thinking of upgrading the wheels I have on it to something lighter. I found some wheels but I believe they would have to have a 9 or 10 speed cassett in the rear. I have 8 speed 105 Shifters on the bike. I was wondering if anyone would like to share their input on this matter, what costs I would be looking at for a new handlebar shifter, would I need a new rear derailuer?
Thanks a lot I appreciate your input -

To go to a 9 or 10 speed cluster you need 9 or 10 speed shifters. You may or may not need a new rear derailleur, you might get away with simply adjusting the limit screws. Someone more familiar with this modern stuff can tell you whether the rear spacing is the same for 8 speed and 10 speed, and if it isn't I wouldn't advise spreading an aluminum frame. Maybe someone else knows whether an 8-speed cluster will fit on a 10-speed freehub, if they are the same brand.
Another option is to use your existing hub and lace up a new rim onto it.
Why do you want a ten speed cluster? 16 gears aren't enough? If it's just to get a lower climbing gear or a higher top gear I would just get a different 8 speed cluster. -

I was looking into putting bontrager race X lite wheels on the bike but I wasn't sure if an 8 speed cassett would fit on those wheels. From what I was able to gather from the people at Trek it wouldn't fit, otherwise I would just use my current cassett. -

The frame should be spaced 130mm, but when you assume you make an ass out of u and me, as the saying goes. But yeah, you'll need a shifter. As for 8 speed on the Bontragers, it'll work fine, but you'll have to put a spacer on the inside of the cassette, and/or re-dish the wheel. May I suggest a wheel without a paired spoke design? Mavic Ksyriums are always a solid choice, I've seen some that were terribly abused but held up. Also, Specialized's Roval wheels are high quality and price competitive. You could always do up the hub you have now to an Open Pro, a solid choice. I just dislike paired spoke wheels because you have to tension them weird, and they always seem to go out of true between the spokes. I'd just go with a traditionally spoked wheel, even if it's low spoke count, I think they'll work out better. -

To go to 10 speed, you won't need a new derailleur, but you'll need to brifters. It's going to start getting expensive really fast. Brifters, cables, wheel, cassette. Also, don't assume that low spoke count, paired wheels weigh less. Look at all the numbers and weigh your current wheels. Figure out how much benefit you'll get per dollar.
I'd only increase the number of gears if I was going to benefit. So I'd do what SkidMark says: put a new rim on my hub. Or, if the wheels themselves would be a benefit, I'd go for the spacer option.
But if you decide to go the other route, let me know. Since "no one" wants 8 speed stuff, I'll be happy to take it off your hands.
