Another day, another wheel (and so on).
A customer from out of town had me rebuild the rear wheel on their ZIPP 404
to convert it to 11-speed and tighten everything up properly.
I'd had it in the shop for a while.
So the other day when they came to pick it up...
Sorry. That's a different job（→this one）.
Turns out it was another 404 of the same model.
This is the generation before they added dimple texture to the rim sidewalls.
The rim width isn't as wide as the current model either, and
the spec doesn't allow for fitting nipple washers inside the rim.
（You can squeeze in a smaller one, but there's not much point）
This is a 188 hub from the days when the freewheel side used radial lacing.
With ZIPP rear hubs like this, from a certain era onward
they all got called 188 but kept changing the specs, which is confusing as hell.
Built it up.
24-hole Evolite hub, half-comp four-cross lacing pattern with tie-ins.
This ZIPP 404 rim is from when they made them at their lightest,
lighter than before and lighter than after.
The current 404 model has the Firecrest profile
with a 27mm brake zone width, making it extremely resistant to buckling
（aerodynamics are beyond my knowledge）,
but that means the weight is higher.
The lightest-era 404 is a rim that's extremely difficult to tension spoke tension on—
even I get quite a bit of dishing issues with it.
The rim height measures 58mm actual, and the height-to-weight ratio
when dividing measured rim height by measured rim weight is pretty impressive.
To calculate this you obviously need the actual measured rim weight,
but I'm not putting that here.
If only I know it, that's fine. Ptui!
↑ man this guy's got a bad attitude
Sorry for the wait!
Please take a look at this image!
↑Oh come ooooon!
