Rotor rex 3 crank and bb assembly

[devinci]

I have this rotor rex 3 crank that i will need to move between a bb92 frame with a pressfit shimano bb and a frame with a 73mm wide bb with external cup bearings. The crank comes with 2 spacers and 3 orings. My understanding is i need all spacers and orings for the external cup bb. Do i need them also for the pressfit shimano bb on the bb92 frame?

Thanks for your help weenies as always

I think it's the same on both if I remember right

This is a rex3.2 or a Rex 3.3??? Normally must come with 4 spacers, and 3 o-rings. And you are using 2 spacers and the 3 o-rings. The spacer size depends if it is double or triple..

I have a 3.3. It's mounted on a P2M single ring. It came with 2 spacers which are 10mm thick judging by eyes.

I installed it on my BSA frame using both spacers. Wondering if its the same for the bb92...
