I received a Kixilium wheel from a customer.
It has the same name and specs as the Kixilium I worked on recently,
but the stickers are different, probably due to a different year model.
The front wheel was built really well—centered perfectly with almost no runout.
The rear wheel has a slight centering issue.
Unusually for an R-SYS system, the rim is biased toward the freewheel side,
but I don't want to loosen the freewheel side,
so I need to remove the dura-comp ring first.
Also, the freewheel-side tension was a bit loose,
so while the centering offset initially increased, I tightened the freewheel side first,
then dialed it in by increasing tension on the non-freewheel side.
This alone wouldn't be complicated, but with R-SYS systems there's still an issue.
Actually, I haven't mentioned this before, but
when you press-fit the dura-comp ring, the wheel center shifts.
So I have to account for that shift and adjust so the wheel centers correctly
with the dura-comp ring in its pressed-fit state.
The Kixilium 125-type rim is pretty light, and I'm getting the sense that
the amount of center shift caused by pressing the dura-comp ring
is larger than with traditional rims.
The images above show the state after the dura-comp ring is pressed in,
but getting to this point took an awful lot of time.
