I have a '00 Bianchi with Record and I would be hard pressed to say it has over 2k on it and the BB is kaput! these new sealed units are sometimes (like everything) hit or miss. most BB likes yours might go 10k but if there was a bad ball in the batch yours came from you may have been lucky to get 4k on it.
