88mm shell, pressed in bearings retained by circlips, you'll have to reuse the square taper axle.
It's a great bit of kit.
Personally, I've always thought this type of BB is way better than UN-whatever Shimano types. Lighter, cheaper to fix and you never have problems with previous owners chewing up the threads, as there are none! So long as you don't break the axle........
