Wheels again today (and so on).
I built the rear wheel for a fixed gear bike
with a Tni 38mm high-profile carbon tubular rim
that a customer entrusted to me.
↑Right side nominally, based on the orientation of the hub shell logo
↑Left side nominally, based on the orientation of the hub shell logo—
the side with the bearing adjustment locknut
RAKETA brand double-threaded fixed gear hub
24H black CX sprint—JIS spoke pattern lacing.
I'll do the full cross lacing on both sides later.
Going back in time, here's the hub by itself.
After this point, for workflow reasons,
I removed the end bolts and lockring.
The lockring is mounted on what would be the right side
when the hub shell marking is at the top
and reads correctly in normal orientation.
Even without it, the left side has the bearing adjustment locknut,
so the manufacturer's intended left/right orientation
presumably has the bearing adjustment nut on the left.
However, this hub technically does have some dishing—
my measurements show the left flange width is 1.2mm narrower
than the right (reverse dishing, in other words).
If using only one side with a sprocket,
the bearing adjustment nut side would be more appropriate,
but treating it as having no dishing and mounting
the sprocket on the opposite side from the bearing adjustment nut
works fine with no issues.
ZIPP makes a ZR1 hub, with a hub shell shaped
like a toppled chess piece, tapered toward both sides.
With disc brake front hubs that have dishing, that's one thing,
but even rim brake front hubs have this tapered shape
and are asymmetrical left to right.
This hub too, though not quite as extreme,
has an asymmetrical hub shell shape.
