Hoping someone can help explain this for me.....otherwise I'll just put it down to Surly.....
I'm currently running the Surly boost fork on my KM. I'm using a Hope hub with a 10mm boost adapter on the non-disc side. The LBS dished it for me as required when using these hope converters to be central in the fork. Its been smoothy all year.
I've recently test fitted a set of boost Fox 34's and the wheel is about 10mm off center in the forks...I guess all forks are not made equal but 10mm seems a lot! I can get the wheel dished again but its destroyed my dream of a hot swapping these forks!
My fox forks have a method of adapting where the wheel sits ( to accommodate slight variations do those ?( Unlikely to make 10mm if difference )
Secondly the hope solution is daft( and weakens wheel due to excess of unequal triangle ) . Centre it and get some standard boost adapters to add 15 mm either side. Which is what I did with my Hope wheel.
Edit : Re the forks deffo BOOST as 10 mm is the boost ! ( That said would still expect a central wheel )
Puzzled by this one. You sure the adapter was on the right side? (sorry!)
Secondly the hope solution is daft( and weakens wheel due to excess of unequal triangle )
If the adapter went on the non disc side and it was re-dished, that would put the rim closer to the non disc side than before/intended and it'd have less dish than a std front disc wheel, I think?

Yep, deffo on the correct side as otherwise the disc rotor position/mounts would be way off.

It's the sort of thing I could do while knocking parts together in autopilot, offering something up without the caliper fitted then puzzle for a mo before seeing my daft mistake..

I know what you mean! The caliper was on so deffo on the correct side. I'll check the distance from fork blade to rim on each side of the Surly fork later on and see if there's a difference
I had a pair of SIDs many moons ago that I crashed, and it must have pushed 1 dropout nearer to the crown than the other, so whilst the wheel was central, the 0.5mm change at the dropout resulted in the rim being 10mm off centre at the fork crown.
Not sure how you'd measure this but turning the wheel so the disc is on the wrong side will tell you if the dropout is twisted or the wheel is off centre.

Your theory is correct, and i was wrong and just measuring one [ no excuses i built it yesterday so should have realised] it makes it[dishing it ] pretty much in the middle by my quick calculation . I stand corrected
