    New Shimmy 10-spd system?

    The new '06 Jamis Nova is FINALLY getting shipped to my LBS, so I am stoked that I will be able to take in a bit of cyclocross in the DC area (right? races....?)

    It comes equipped with the new 10-spd 105 gruppo. does anyone have any feedback on riding this gruppo in the muck? I would think that thin cassettes and thin chains engineered to such tight tolerances would be fine for road, but might get a bit bent out of whack all clogged with dirt and leaves and whatnot.

    I found out that the 10-spd cassette works on 9 speed hubs, with a 1 mm spacer. 1 mm? That's hardly the width of a dime, for cryin' out loud.

    So... 10 speed drives--function or fadshion?

    Ran 10s on both my bikes this season. No worse than the 9 stuff, and I was talking to at least one bike designer who was saying they've had better luck with 10 because the narrower chains were shedding mud easier than the 9 stuff. Personal experience was that they survived the mud of New Gloucester and the snow of Gloucester and Nats.

    Seems like the difference between 9 and 10 is like vanilla and chocolate. I dont know that there is a definitive answer as to which is better for cross. I ran 9 this past season (Ultegra, Dura Ace) and never had any problems. I think the main complaint with 10 is that the chains are thin -- and therefore more prone to breaking. I cant say that I've heard that 10 is better for shedding mud though -- when its muddy its muddy, and 9 or 10, your drive train is gonna get gunked up no matter what. Honestly I think that both 9 and 10 are somewhat un-necessary for cross. I never use all those gears, which is why I'm considering switching to single rings next year.

    Frankly, whether u are using 9 or 10, i think your best protection against drive train malfunctions is having your stuff tuned right, and using a good lube.
