    Moving 2-piece LX cranks from one bike to another ?

    Guys,
    I plan on moving these cranks (Hollowtech II ?) from an Airborne Liberator HT to a Stumpjumper FSR.
    Any things I should watch for before this move? Will there be a chainline issue? I'm an external bearing newb so please bear with me.
    Thanks.

    they might have different BB widths (ie 68 vs 73mm), so you may have to change around spacers or not use 'em on the wider, if one is wider. Assuming the BB can be used on both, and not need a new BB (I believe this is the way the shimano's work these days).

    should be fine...

    I recently switched mine over but like the other poster said
    you might need to change the spacers. The LX Hollowtech II
    will fit on the two BB sizes but you need to have the correct
    spacers (that came with the crank). First you need to find out
    what size BB shell your old frame has and the size of the new
    one. For myself, I had to add an extra spacer. Check the instructions (assuming
    you still have them) to see how many spacers you need for each
    BB shell size. the instructions are also available at the Shimano website.
    If you no longer have the extra spacers your LBS should have them. Your
    new frame/bike should come with something saying what size BB you
    have.

    Appreciate the help. Both BB's are 68mm so I guess I'm good there. I'm hoping I can just pop out the cups, hopefully without damaging them, and get this done soon.
    Thanks again.

    I don't know your level of expertise but when you say pop out the cap without
    damaging leads me to the conclusion that you are unfamiliar with these cranks.
    Then again you might know a lot, but just in case I would suggest that you read
    on the park tool or sheldon Brown website on how t remove these BB cups and
    crank arms. Its really simple but you need the tool. If you have one then you
    just unscrew the caps, no "popping out." The important thing is that you have the
    tool.

    Glad you brought that up. I looked on the Park web-site and had a A-HA moment. Now I see why they say it's so important that the BB is square to the threads.
    Looks like I'm in the market for a BBT-9.
    Thanks.

    I am glad you looked before you started trying to pry them off.
