The front wheel of the R-SYS SLR that I replaced the rim on the other day
I also had the rear wheel of the matching wheel in for inspection.
The area around the disc (tra) ring on the front wheel was covered in grease,
but the rear wheel had nothing applied to it.
A very rare dropouts with four slots.
Well, dropouts with 3 to 1 slots don't come with wheels and are difficult to source.
Jumping ahead in the timeline,
I applied silicone grease to the contact point between the disc ring and the spoke head
and positioned the disc ring so it contacts at a different point than the original contact location.
The freewheel body rotation felt smooth, but when I took it apart,
the interior was depleted of its specialized oil and rust had appeared on the pawls.
I wiped away the dirt, refilled it with the dedicated oil, and reassembled it.
At the provisional centering, the rim was shifted to the left.
This is a characteristic tendency of Mavic wheels, but the amount of deviation is relatively mild.
If this were a new wheel, I'd leave it at that, but
since I later discovered there was quite a bit of lateral runout,
had I searched at the provisional centering stage, there might have been a phase with perfect center or
a different phase with more deviation than in the image above.
With emphasis on tightening the freewheel side,
I intentionally shifted the rim to the right to correct the lateral runout.
I tightened it quite a bit, but
the rim didn't move to the right as much as I expected.
At this point the runout is corrected, so
the result would be the same regardless of which phase I measured.
The R-SYS non-freewheel side has nipples (strictly speaking, part of the spoke itself) with coarse pitch threads,
and additionally has a large amount of offset adjustment, plus it's radially laced, so
the rim movement per nipple rotation is
probably the maximum of any wheel in existence.
The nipple rotation needed to correct the center deviation in the image above is minimal.
I've got it centered.
