One more thing. If you're looking at Krysirums you may also want to

consider Rolf Prima. They have wheels (such as the Vigor) that compare

very well AND they're made right here in Oregon! (You do know Mavic is

French, right?)

I'm sure everyone will chime in with their own opinion but I've been

running my Vigors for two seasons now and have been extremely satisfied.

To sum up, what I'm hearing is that in *most* cases, I can just pop a

new 9-sp cassette on the hub and everything should work just fine with

my existing 9-sp components. Exceptions occur with Shimano wheelsets

using the new, narrower Dura-Ace and Ultegra-10 hubs. The 10-sp

cassettes are backward compatable to older hubs using a supplied spacer.

This is good as I'm not looking at Shimanos. My goal is to get Mavic

Krysirums this spring.



If I do get a 10-sp cassette, then most components of the drivetrain

have to go 10-sp as well; chain, shifters, derailleur, maybe even the

front stuff (crank & deraulleur). Regardless, it's more of an overhaul

than I think the frameset merits at this point. As someone mentioned,

I'm probably better off going to 10-sp when I eventually get a new bike.
