No; redishing is necessary EXACTLY for the reason to keep the rim in the centerline, while pushing the hub sideways. That's why I also mentioned that you have tofiddle with the axle spacers, too.


Anyway, do as you wish, but trust me on this: chainline is critical.
You don't seem to understand what my problem is...

First, I never said I'd move the chainring AWAY from the centreline. It's as far in as it can go already.

1. I can't move the chainring farther in towards the frame. It will then hit the chainstay.
2. I can't move the sprocket farther out towards the fork end. It will run out of freehub splines to engage.

The hub fits precisely into the rear fork end's width - adding a 3 mm spacer on the non-drive side would force the frame to open more than it "should". I'm not sure that's a good thing to do to an alu frame.
