    The bottom bracket width refers to the measurment from face to face of the bottom bracket shell on the bike. The 113mm dimension you have been given is the overall length of the axle for want of a better word!
    The best way to be sure is to measure whats on your bike at the moment.
    Both dimensions are critical, firstly so the thing will actually fit your frame and secondly to get the correct chain line.
