    dropping chain after converting to 2x9

    i put on rotor 3d 2x9 (40, 27) and adjusted my xtr front derailleur, left everything else the same. everything works nice except i'm occassionally dropping the chain off the big ring when coasting through some rough trail. any ideas on whats happening?

    Is your larger ring the same size as you had before? If no and it's smaller, you will likely need to shorten your chain. There are many tutorials on the web for doing this if you're not sure how to get the length right.

    If your chain length is already correct, I'm not sure what could be causing you to drop the chain.

    I can barely get my mouth around it.
