    difference between bb30 bearings and bb30 bottom bracket

    I am sort of new to the mechanical side of bikes and would like to know what the difference is between BB30 bearings and a BB30 bottom bracket bearing assembly. I have a bike with BB30 frame and am looking to switch out my Apex for a Force but I see both of these items listed.

    Thanks
    Brian

    A BB30 bottom bracket consists of the frame BB shell, two metal clips, two cartridge bearings, two dust covers and spacers. The bearings are the consumable part, but you need all of it, one way or another.

    Don't confuse BB30 with Press Fit 30. They work on the same cranks, but require different cranks.

    So I need the bb30 bracket assembly and the bearings plus the Force crank set and then I can swap out my Apex

    as far as i know Apex is only available in GXP. if you have it now, you're frame isn't BB30. why are you buying a BB30 bottom bracket and crank if you don't have a compatible frame?

    cxwrench the frame is BB30 with a pressed in adapter and that is why I want to change it to BB30 Force. Thank you for looking out for me just in case I was about to make a mistake.

    just make sure that whomever presses the adapter out of your frame knows what they're doing and uses the proper tools. they're technically 'removable'...but it's not recommended. in this case, you will need the BB30 bottom bracket kit, and the proper crank. Force is a good choice.

    cxwrench They make the Force in a GPX version. Would that be an easier swap and would there be much difference in feel and performance over the BB30 versions?

    Thanks

    you'll never notice a difference in the cranks. if you have the adapter installed, i'd recommend getting the GXP crank/bb and use that.

    The BB30 cranks have a lot more ankle clearance - the most of any crank. Some people complain that they actually scrape themselves on the GXP crank's raised center spindle.

    If that isn't you, then don't worry about it.
