E13 BSA 30mm BB and the BB is "open" in between the cups, no "tube". So the bearings weren't the worst I've ever felt, but they needed replacing...they were damn near welded to the spindle though. I had to pound one of the bearings off with a punch bit by bit. Corrosion on the spindle. I cleaned it really well, wire-brush and some corrosion cleaner/inhibiter. Put some new SKF bearings in there. It's baby-butt smooth now, but I wasn't expecting to have bearings jammed on the spindle when I took it apart.Man you really must have killed em, mine have always just beenView attachment 165120
