Rebuilt the front wheel on a 202

A customer brought in a ZIPP 202 front wheel for me to work on.

They wanted it rebuilt for a specific reason.

There's a recall on two types of flange-ring style front hubs,
and this is an 88 hub—the type where the ring extends inward like a dust cap.

I loosened the nipples over a bit more than half the wheel.

Once you release the spoke tension enough, the flange ring comes off.
Because of this design, replacing even a single spoke on this hub requires
loosening all the spokes on one side first—it's a real hassle.

The spokes are hooked-on, so I can remove them one by one.

I did the same thing on the other side and removed the hub.

By doing this, I can collect the spokes without loosening all the nipples completely.

They have straight spoke heads, so

they'll fit through the rim holes.
The ZIPP has a tube still inside the rim, so if you drop a nipple inside it's a pain to fish out.
This way avoids any extra hassle.

Got it built.

Evolite hub, 18H, black CX-RAY outpoke radial lacing.
The customer also wanted black spokes.

The manufacturer's recall notice only mentions the flange ring issue, but
this hub can also fail in ways that suggest the hooked-on design wasn't strong enough, so

the next model's hooked-on hub flange is noticeably thicker.
