A customer brought in a Racing 1 for service.
It's been inspected at another shop before,
and since it's been in use for a while, the customer wants a full overhaul.
There was almost no lateral run-out.
As for wheel centering,
the front wheel is perfect.
The rear wheel rim is shifted toward the freewheel side by about the thickness of a sheet of paper,
but with R-SYS hubs other than R-SYS, the rim tends to shift this way with age,
so I suspect it was perfect when first adjusted.
The customer mentioned the freewheel body was later swapped out for a Shimano 11-speed version,
but that wouldn't affect the centering.
The hub bearing adjustment feels just right with smooth, clean rotation,
so I do feel some hesitation about doing the overhaul as requested.
I disassembled it.
Cleaned it thoroughly and regreased everything.
The bearing races have clean, perfect tracks and the rotation is exceptional.
The steel ball bearings spin even smoother than a brand new CULT (オフザシェルフベアリング) unit hanging on the shelf.
The pawl return spring on the freewheel body isn't bent either.
The axle is from an era before butting was common, and while there are faint traces of rubbing just below the bearing seat,
there's no rust transfer or scratches. The condition is excellent.
The customer's request was to replace any parts that need replacing,
but there were no parts that required replacement.
Between the spoke heads and hub flange, adhesive has been applied to prevent noise (on all but the freewheel side of the rear wheel).
The appearance isn't great, but it's hidden by the dust cap anyway,
and it does work effectively (though I don't do it myself).
Next up is the R-SYS SLR (Ritey custom hub).
Since it belongs to the same customer as the Racing 1, I've put them in one post.
The front wheel has no centering error,
but the rear wheel showed the usual offset pattern.
This rear wheel didn't have loose spoke tension,
so if I just centered it without removing the truing ring,
that would be sufficient. But since I wanted to apply grease to the spoke heads,
I removed it temporarily. The front wheel had slight run-out, so I removed it to true it.
The image above is the front wheel.
