A customer brought in the front wheel of a ZIPP 404NSW for repair.
ZIPP's new series of full-carbon clincher wheels is called
NestSpeedWeaponry, and this is the 404 version.
Apparently "Nest" refers to their own manufacturing facility.
It uses an ultra-wide flange front hub body with a thick shell,
but you need to be careful as some fork designs can cause clearance issues.
↑concrete example
The customer said the wheel has runout and wanted it trued.
↑touching the gauge lightly
↑significant runout here
This looks like the kind of runout caused by a bent spoke mixed in,
so I checked the spokes at this phase position and found
It appears to be bent. You can feel it faintly when you run your finger over it.
I released the tension.
I'll repair it with the CX-RAY straight spoke that we use for repairs.
This time I'm using a 270mm spoke that can be cut down to 240mm,
and since the original spoke length was in the 240mm range,
the butted section transition didn't shift too much.
↑original spoke on top, replacement spoke on bottom
The plain length on the hub side is nearly identical.
Since it's designed to be cut, it has no threads.
The plain length on the rim side was also nearly identical.
↑perfectly centered
The end caps look identical on both sides, so I shot it to show the hub shell.
The end caps look the same on both sides and are the same part on both sides,
but the axle has left and right distinctions.
This is a front hub from ZIPP's Cognition model,
and it uses a press-fit snap-on end cap that requires
a hub axle wrench and vise to remove the end cap.
Hubs like the Evolite front hub or Power Tap rear hub have
loose snap-on end caps you can remove by hand,
while DT hubs use the press-fit snap-on type,
but neither has a bearing adjustment mechanism.
On this hub, a wave-form C-ring is fitted on the left side
to absorb some of the bearing play,
so while there's no bearing adjustment mechanism, it's designed
to resist play developing. It's somewhat similar to
the bearing area structure of a Campagnolo Ultra Torque crankset.
The brake zone has treatment similar to Campagnolo's AC3
(All Conditions Carbon Control), and ZIPP's name for it is "Show Stopper."
Show Stopper means
"applause and acclaim so thunderous it stops the show"but can also mean
"a defect so severe it was discovered during product development and delayed release".
If they're calling the noisy braking sound a show-stopping standing ovation as a preemptive jab at criticism, that's a pretty clever move.
↑There's a specified direction of wheel rotation.
By the way, Campagnolo's brake zone is actually AC3
(All Conditions Carbon Control), not D4C. Let me correct that.
