Rebuilt the rear wheel on the 303

Another wheel day (and so on).

A customer brought me a ZIPP 303 rear wheel to work on.

The ZIPP rear hub on the freewheel side with radial spoking
has gone through two generations — silver hub followed by black hub.
Only the black hub accepts a Shimano 11-speed freebody,
but this one is forced into 11-speed configuration by fitting
a black hub shaft and end cap onto the silver hub body.

But there's something odd — the left dust cap is stacked double.

And the centerline is off.
On this hub design, the end cap position doesn't affect centering.
Even removing the extra dust cap won't change the amount of centering offset.

The dust cap has a flat outer surface,
and a stepped inner surface designed to press only on the bearing's inner race,

but the extra dust cap is installed with the stepped side facing outward.
Either direction doesn't affect dimensions or bearing adjustment though.

The reason for doing all this is
DSC03600amx8.jpg
the left side width of the hub body differs between silver and black hubs — the silver hub is narrower.
When you fit a black hub shaft, the threaded section for the bearing adjustment locknut
ends up stopping partway through.

↑That's the situation.
By the way, even though the hub body width differs, the flange width is the same.
And just to be clear,
I'm not actively collecting rebuilt ZIPP hubs for myself.
I only take them when the customer says they don't need them.
I'm returning this hub to the customer too.

All built up.

Evolite hub, 24H, black half-comp with 2-cross lacing and black aluminum nipples.
I'll tension the spokes later.
The hub choice and lacing pattern are what the customer requested.
The switch from silver spokes to black spokes is because

the matching front wheel, which is in for inspection,
is from the black hub generation with black spokes and black nipples.

That one was dead centered and had almost no runout.
The hub bearing had some play, so I cleaned that up before doing the truing work.

By the way, this rim was lighter than I expected,
but I have no intention of telling you the specific weight. ←wow this guy is really unpleasant
