A customer dropped off a rear wheel
with Racing Zero tubular rim specifications.
They thought there might be an issue with the hub,
but there wasn't anything particularly wrong.
There was some minor runout, so I corrected it.
Separately, I also received
a Continental tire that
wouldn't fit because the inner diameter was too small.
I stretched it using a stretcher Y
and mounted it to the rim without cement.
It's a Competition Pro Limited model,
and starting directly below the valve hole
at a 120° phase difference,
there's the Continental marking in gold lettering,
which is different from retail versions.
It says 25mm RBX,
but I'm not sure what RBX means.
From ones I've seen before,
it was marked 28mm PTX.
The stretcher Y doesn't get much use these days,
but looking at past posts, most jobs
have been stretching high-end Continental models.
