I had a pressfit-86 frame BB warrantied and have to move over all the parts to the new frame. The BB is practically new. Is it straightforward to move the BB (incl. the pressfit cups - are the cups reusable?) to the new frame? I see that this requires some special tools (to do it neatly at least) which I'm not sure my LBS will have. I would like to move the BB over and avoid buy a new one if it's easily doable.

Also, when the bearings eventually die, does the whole BB need to be replaced or just the bearings (if that's even possible or do the bearings and the cups form a single unit)?
