• Can’t believe I’m being confused by bb spacers but these cups won’t tight up flush against the bb shell while the axle sleeve is installed.
    I’ve took the sleeve out and they tighten down fine.

    68mm shell means no 2.5mm spacers between the cups and frame, right?
    I’m guessing the axle sleeve has been incorrectly machined but I bought three of these Nukeproof bb’s in the wiggle sale and the axle sleeves all measure the same with digital calipers.
