Yeah ive actualy did that to a past bike of mine. its odd though I put this BB in not a long time ago. and its the none drive side. its a sealed BB and somehow one of the sealed bearings that usaly dosnt come off is stuck with the cup on one side. the cup is one of them new kinds. I have the tool to remove them. its literaly stuck and keeps breaking insted of comming out dispite the heat I use or chemicals. I knew I should have put a traditinal BB in it.

In the end I dont mind to much. I bought a new 29er recently and my old one I dont wanna let go of because its got value to me still. ill put it on the xtracycle attachment if I can fit it.

thanks for that tip I may do that to my other bike.
