I recently replaced my 11.7" rear rotors with new ones. The fit was tight enough around the hub that I resorted to a rubber mallet. Because of a seal leak, I'm replacing axles. I tried the old rotors on the new Moser axles and the fit was a tad loose--no such thing as using a mallet to put them on. So, could there be a difference in the rotors (or could there be a difference in hub size between the two axles)?
