The bottom bracket shell width is 73mm. For those of you running three-piece cranks, your spindle width will depend on the crank you're using. As examples, Shimano's cranksets commonly used a 112.5mm spindle (for Hollowtech I) while ISIS-based systems were generally used with a 113mm BB spindle length. For fitting any of the newer two-piece designs it's just a matter of using the appropriate spacers provided with the BB cups.
