    Mountain Bike Parts To CycloCross Bike

    I've got an older mountain bike with some great parts (Shimano Deore XT). I'm ASSUMING I can use the derauillers, brakes and probably the cranks (correct me if I'm wrong). Its not a big deal but as long as the threading is the same, can I also use the bottom bracket?

    Thanks

    Keith

    What kind of bike do you want to put them on?

    you can't use a MTB FD with road STI levers, the cable pull ratio is different.
    if that's what you intend to do...
    Food for thought: if you aren't dead by 2050, you and your entire family will be within a few years from starvation. Now that is a cruel gift to leave for your offspring. ;)

    True. The bike in my earlier post has an Ultegra Triple FD and STI's.

    The crankset might have the wrong chainline - spaced to match a 135mm MTB hub rather than a 130mm road hub. Aside from that, I can't see any issues.

    the XT cranks are spaced for OS 73mm instead of 68mm so you will need to add spacers to the BB for outboard BB.

    The XT BB comes with spacers.
