A customer brought in an R-SYS SLR for service.
They're requesting an inspection. Starting with the rear wheel.
When I spun the freewheel body by hand in reverse, it felt sluggish and had a lot of resistance, so
I cleaned it out and applied dedicated freewheel body oil.
Also, the right end nut was loose,
which would affect where I position the centering gauge,
so I tightened it properly after the service.
The wheel center at that point was
Unusually, the rim had shifted toward the freewheel side.
The R-SYS SL hub uses
a QRM SL quick-release end without cone adjustment,
but there are marks showing someone removed the end
without using a proper hub cone wrench—
they grabbed the flange part that contacts the frame with a tool like pliers.
I centered it up.
Next, the front wheel.
Even accounting for the fact that these are Mavic wheels, the amount of runout was significant,
and there's not just lateral runout but pronounced radial runout too,
so I suspect—without asking the customer—that someone's been playing around with spoke tension.
Given that, I'm thinking the rim being shifted toward the freewheel side on the rear wheel
might have been caused by that too...
Well, as long as it gets fixed, who cares.
Fixed.
The end shows more wear than the rear hub,
but on the R-SYS SLR front hub,
the hub axle and right end are molded as one piece,
so only the left end can be pulled out.
From the factory, based on the direction of the logo on the hub body,
the left end is the one that comes off
(unless someone mistakenly installed it backwards later).
