    2 x 10 crank with 9 speed shifters etc?

    Can I put an XTR 2x10 crank on my race bike and run it as 2x9 with my current XTR 3x9 speed set-up?

    I'm not 100% sure on this but from what I gather it should be fine so long as you also replace your front derailleur and shifter to the 2x10 versions. Hopefully someone else can correct me if I'm wrong or elaborate on why you'd need to do this.

    you can keep your 9-sp rear shifter, rear derailleur, and cassette.
    2x10 cranks will require new/matching front derailleur to shift properly, plus a new front shifter.
    all this will work with a 10-sp chain, not sure about 9-sp with the new chainrings, but you'll need to replace your chain anyway.

    apparently you can use your 3-position front shifter, but have to use position 2&3 (as opposed to 1&2 like you would if you replaced the big ring with a bashguard). if this is true, it would save you a few bucks, though i doubt that matters if you're contemplating XTR cranks!
