    135mm or 130mm hub?

    In theory a 130 mm hub, when adding a 5 mm spacer to the non drive side and re-dishing the wheel will fit a 135 frame, with no derailleur adjustments, correct?

    Yes, that's true in theory. Since the distance from the first sprocket (anf by extension all the others) to the right dropout is unchanged there shouldn't be any needed adjustments to the RD.

    that's the theory, but don't be surprised if you end up doing some minor trim adjustments, because bicycles are contrary and won't let you skate just because you're right in theory.

    In my mind, you might have to slacken the RD cable a bit, since the right dropout will be 2.5mm to the right.

    Oh wait, do you mean swapping a totally new wheel into a 135mm frame? Slight derailer adjustments there are almost guaranteed, since not all hubs put the cassette in the exact same spot. It is, however, possible to carefully space your rear wheels so they swap out exactly with no adjustments.

    Yes, I've adapted Shimano "road" hubs to 135mm OLD frames by spacing out the left locknut (I swap the axle, too, but that's not always necessary). If you're moving within the same manufacturer, (i.e. Shimano for Shimano) you should have no problem. Per Jake, no guarantees between manufacturers.
