Bottom Bracket Shell Width measurement

I have a vitus 992 and I wanted to measure the bottom bracket for replacement. However there seems to be a black rubber ring on one side of the BB shell and I was wondering if that is to be included in the measurements. I have attached a picture. The black ring is on the left side of the picture right beside the serial number.

...no. That's either a spacer (dubious) or more likely the lip of the threaded cup that holds that part of the unit in place. Just measure the shell.

BB shell width is just what it says it is. The width of the frame's BB shell, exclusive of any added spacers. I suspect that the 2mm(?) spacer was added wither to improve chainline,or to fit a spindle made for a 70mm BB shell.

Great thanks. I just wasn't sure if it was a part of the frame.
