I received an R-SYS SLR from a customer for inspection.
They wanted a checkup. Let me start with the rear wheel.
When I spin the freewheel body backward by hand, it feels sluggish with a lot of drag, so
I cleaned it and applied some dedicated freewheel body oil.
Also, the right end nut was loose,
and if left that way it would affect where I can place the centering gauge,
so after the work I tightened it firmly.
The wheel center at that point was
Unusually, the rim was offset toward the freewheel side.
The R-SYS SL hub uses a QRM SL end, which is a press-fit design without ball race adjustment capability,
and there are marks showing it was removed not with a hub cone wrench but by grabbing the collar that contacts the frame with pliers-like tools.
I got it centered.
Next, the front wheel.
Considering this is a Mavic wheel, the amount of deviation is quite large, and because there's not just lateral runout but also notable radial runout,
I haven't asked the customer, but I suspect there's a history of amateur truing attempts.
If that's the case, then I'm thinking the rim being offset toward the freewheel side on the rear wheel might be a result of that too...
Well, as long as it's fixed, it doesn't really matter.
Fixed it.
The marks on the end are more noticeable than on the rear hub, but
on the R-SYS SLR front hub, the hub axle and the right end are molded as one piece,
so only the left end is the one that pulls off.
In the factory configuration, based on the orientation of the logo on the hub shell,
the left end is the one that comes off
(unless someone later installed it backwards by mistake).
