Is it possible to convert a square hub to an ISIS mount.
Do you mean:
- Is it possible to use a square hub into an ISIS frame? => Yes, with correct shims.
- Is it possible to use ISIS cranks on a square hub? => As far as I know, no.
I mean the recording of the cranks that you convert them and the Hub a Adapter from square Hub to ISIS.
No, that doesn’t exist. And there is not enough of a difference in diameter between the two for an adapter to work (unless you are willing to move the cranks very far outwards.).
