Can anyone answer this question?

I have a squeaking dura ace 7800 bottom bracket which needs to be replaced. I know an ultegra will work with the dura ace crank, but is there any difference in the quality of the bearings between the two?

Thanks,
Jeff

I would say that both are comparable. However, I have read that Dura Ace puts a longer lasting, nicer finish on their products. I have also read that the Dura Ace group generally has better springs than the ultegra. As far as the bearings, I do not know.
