Another day working on wheels (long story).
A customer brought in a rear wheel from a ZIPP 404.
Not that it matters for the work, but it's a WO rim.
It was laced with a 20H rear hub that couldn't be upgraded to 11-speed, built to roughly Zometerny lacing standards for 10-speed. The customer wants it converted to 11-speed.
Goes without saying, I'm rebuilding it tighter than the original, though honestly building a looser wheel than this one would've been harder.
There was no centering offset, but I found one spot with a noticeable lateral wobble.
If I'd placed the centering gauge right at the worst deflection point, I might have caught an offset.
↑ This is the final lacing pattern after releasing tension, but
↑ At a different crossing point, there was one spot with deformation like something had been hit from the side.
From another angle.
That lateral wobble I mentioned earlier—it's quite likely at the same phase point directly below this. I'm not going to tension it again just to verify that though.
I recovered all 20 nipple washers.
16 of them were oriented correctly relative to the rim's front-to-back direction,
but 4 of them had been tensioned sideways, which bent them to follow the curve inside the rim.
As I've mentioned before, these are Sapim parts, not ZIPP-specific, so they're available—we have them in stock, so I'll replace them.
Built.
