How can i find out my BB size without taking it out??? By the way i own 04 Norco Wolverine.
Thank you!!!
Shell width (68 or 73mm) can be measured directly across the frame, as in the photo's I've attached.

Spindle length can't be measured without removing the crank arms, but there is a chance it is imprinted somewhere on the exposed portion of the spindle, between the crank and the flange, or imprinted on the flange directly.
