Hm, I’ve always tended to remove tyres before doing anything with spokes. I guess that’s another option.
Centring… it will be off centreline, there would have been no point redishing to compensate for an extra 6mm in the DS endcap otherwise. Visually, I can’t see it’s overly close to either leg although it must be about 3mm closer to the NDS (?) I guess.
I’m not so worried about handling. What I was wondering was; Given it’s true, I’m worrying over nothing, yeah? Or would the wheel be better with the dish corrected as I have obviously slacked one side a turn and tightened the other? My thought is, as it’s straight and I’m not noticing a problem the tension per side must be pretty even?
