With different model hubs, you sometimes have to juggle axle-spacers to move the cogs in and out so that all the wheels have cogs in the same place, making wheel-swaps simple.
Of course they do, the also prevent your bike from exploding. Which is why I said "ignoring the limit screws on a wheel swap" advice is the worst you could possibly give.
Limit screws don't affect shifting? How about blindy screwing the H and L screw all the way in. Still shifts into all your gears? Didn't think so. Thanks for playing.
