I received a Racing Zero from a customer.

It's a tubular version of the Racing Zero that's already been discontinued.
Let me start with the front wheel.


The customer had put marker tape on a bent spoke.
The spoke was bent in the direction that something got caught during rotation.


Fixed.
Aside from the nipple on the replaced spoke, I barely touched anything else.
When I removed the lateral runout, I checked it with a centering gauge for the first time,
and it was perfectly centered.
That means the original state was nearly runout-free and perfectly centered.


Now for the rear wheel.


You don't get damage like this from riding. Someone twisted it by hand.
The customer didn't do this themselves.


I managed to fix it.


By "managed," I mean
there was deformation in the rim right around the phase where the spoke was twisted,
so I couldn't completely remove the runout.
The rim was bent in the rest phase near the final crossing between spokes on the freewheel side,
and there was honestly not much I could do about it.


↑Replaced spoke


A twisted spoke definitely needs to be replaced,
or so I thought, so I tried a bit of last-ditch effort.
It didn't work.
