Im looking to make my wheelsets more interchangable between my Nukeproof Mega and Reign ebike. The ebike has a 220/200mm front and rear, the Mega 200/180. Both use post mount, both Rock Shox (Zeb and Lyrik) and SRAM Code/Guide brakes. I have rotors, what do i need in the way of adaptors?
Two +20 mm adapters.

might need some shims to get the rotors in the same place.
cheers - will this work on both front and rear?

Yes. As long as you have a 20 mm adapter, it will space any caliper out 20 mm. 160 mm to 180 mm, 180 to 200, 200 to 220, front or rear, it shouldn't matter.
This might not quite be correct - it depends what is there already. You don't want to be stacking 2 x +20mm adapters on top of each other!
You might have a +20mm adapter on the forks already, in which case you should be able to move that to the rear (assuming there is no adapter on there) and just need a +40 for the front.
Yes, you should check what's there already. Good point.

That would be true of you were just stacking on top of existing adaptors, but not right here.
Zeb has a 200mm post mount, so needs +20 to take a 220mm rotor. Lyrik depending on age is either 160 or 180, so needs +60 or +40 for the same rotor.
Yes, as tomnavman pointed out, it really needs to be an adapter that is 20 mm larger than whatever's currently there.
