How wide is an Shimano BB supposed to be?

[eurodude]

I just installed a Rotor PF BB for the Shimano 24mm axle system on my frame, but i noticed that when the BB is installed it is a bit wider then the Shimano Ultregra BB i had on my other frame with threaded shell?
As far as i can measure the Rotor is 93mm and the Shimano is 90?

It depends on which model. They have them for 86.5mm width, 89.5-92mm width, 104.5-107mm width.

Depends on the model.

The Rotor BB? I got the Road version, so it should match up with the Shimano road BB?

-Edit, removed because I'm no longer sure-

But I think for road it should be 90.5 or 91mm. You'll know if you're off, you won't be able to seat the little retention pin that hinges on the crank bolts.
