That's really interesting. In my experience with the Diamond and Onyx, the HSC dial is very stiff, and is probably the last adjustment that would ever self-adjust during riding. So stiff that I usually need to use the LSC adjuster, at it's max or min extent, to help wind the HSC adjuster in either direction. Then I reset the LSC to where it should be.
Yeah that's how mine is as well, no way HSC would move on its own. I wonder if he means the OTT?
Nope. HSC.
And yes, it's stiff AF to turn by hand. Unless a buddy has been messing with me, or I've been turning it without updating my note file, it's turned just through use.
I know it sounds super unlikely, and I was very surprised to find it, but just as a data point to check if something feels off, there you go.
Fair enough. I'm on 3 different DVO forums, and two Ibis Ripmo AF forums which are bikes that almost exclusively include Diamond and Onyx forks. I've never heard of HSC self adjusting, although OTT is a bad one for self adjusting (as Kenny mentioned), and LSC is easy to bump out of position by accident.
Then looking at the mechanism itself, if the knob is very difficult to turn by hand, it's going to take a lot of force for the internal assembly to self-adjust, and that stiff knob will turn along with it. If I were you, I'd use a paint pen or silver sharpy to mark the setting position, ride a bunch, and confirm for sure that it's self adjusting. If/once you confirm for sure, that's a specialty question for DVO (they're VERY helpful with end user communications), because your problem itself is "as rare as hens teeth".
