Hi everybody

I have a sealed bottom bracket (Shimano Ultegra: http://www.jensonusa.com/store/produ...m+Bracket.aspx)

and I'm having problems threading into onto a new caad9 frame (http://i38.photobucket.com/albums/e1...pboard01-3.jpg).

The left-side (non-drive) threaded on fine, but the drive side threads wouldn't watch; it just kept turning. I tried putting left side in first, and right side first. I didn't mess up the side each cup goes on, and was turning them the right way.

Anyone have any ideas?
