Are these the ones you mean?
So you only can vary the FDR with the spur? (as to an FDR that would need a pinion > 32T)
Not with the pinion because the HMX needs long boss?
A bit of a hassle, isn't it? Or is the spur on the HMX interchangeable in an easy and quick manner?
Isn't there an alternative for the Corally long boss pinions? (especially when needed >32T)
If so which ones?
