    Light weight 9 speed cassette for race bike

    Hello Drivetrain experts.

    I will be building up a lightweight racing carbon hardtail as a racebike. I have a spare SRAM XO 9 speed derailleur and some XO twist shifters I'd like to use. I am debading between two cassettes:

    http://www.sram.com/sram/mountain/pr...g-999-cassette

    http://fairwheelbikes.com/kcnc-9-spe...ano-p-602.html

    I would suspect that the SRAM may shift better and is "in keeping" with the other rear components, however, I have heard that this design is hard on the hub driver. The wheels are built on Extralite hubs, and I can't recall whether the driver is made of Aluminum or Titanium...

    I would probably prefer the SRAM cassette, but if they are known to shred drivers, then that is a definite consideration.

    Does anyone have experience with either or both of these? Of interest to me is shifting performance, durability of the cassette, stress/wear on the driver, and anything else that may be worth mentioning.

    Thanks for any and all intelligent comments.

    I prefer cassettes where the larger sprockets are on hubs (spiders) in pairs or threes. The extra width where the spider meets the freehub body reduces nicking and gauging. Most better cassettes are built this way.

    Loose cogs are fine for the outer ones because their smaller diameter means less torque for any given chain tension, and generally riders aren't torquing their high gears the same as they do the low gears in hard climbs.

    Besides Shimano, there are also 3rd party producers of cassettes with hubbed larger sprockets.

    It's a typo, fat fingers on a small keyboard. Try better.
