Schwinn moab3 BB?
 

If anyone knows the size of a 99' schwinn moab3 bottom bracket, I would be ever grateful. Normally I would pull the thing and get the size, but, Im 2 states away for the moment and need to pick one up and replace it when I get home.
Thanks for any help! Oh, the frame size is 23" if it makes a difference. The bike is stock with the blue/white metalic paint job. Thanks again!
