Will I need a new BB...

If I change my 2014 tripple crankset to an XT double will I need to get the BB replaced or will i just be able to swap the cranks over and keep the BB that comes with the new cranks as a spare? Current cranks have only done 700km.
Remember Rule #5

If you're changing from a Shimano Hollowtech 2 chainset then yes, you'll be able to keep you BB. Anything else, it's a maybe.
