What? Done all the time in shops and at home. But since we don't even know what type of Bb the OP has for real, only the listing of a Madone in his house. But if it is the Madone even more so the BB is very easy to take apart.

They're too cheap not to replace.


Agreed but that wasn't the question.

My guess is they spun the cranks, either felt or heard roughness/looseness and said the BB will need replaced relatively soon. They're probably not wrong.


As I also mentioned and I again agree that they are likely not wrong in that the BB is worn.

EDIT: As for the OP. There is almost nothing you can damage by using a worn out SEALED BB. It'll just affect your ride quality. Ride it till it falls apart if that's your desire. Or, fix it. They're only $20 or so for good BBs that'll probably last 1000s of miles.
