Another wheel day (and so on).
Built a front wheel using Light Bicycle's
ultra-lightweight rim with no holes on the outer edge
except for the valve hole.
Extra Light Cyber Front SPC 3+
Front hub, 24H, all black CX-RAY
Left and right, forced 2-cross lacing.
The Extra Light front hub
has all its hub shell logos reversed.
Since "Cyber Front" is the hub model name,
for rim brake hubs
I used to write
"Built a front wheel with the Cyber Front front hub,"
but this hub is the
Cyber Front SPC 3+ model.
SP stands for straight-pull specification,
and for 6-bolt rotor mount hubs
it was SPD with the disc D added,
and then later the center-lock mount version
was called SPC with the C added—that's the naming convention.
As for the "3+," I'm not sure what it means,
but it used to be just "3" not long ago,
so there may have been some minor revision.
↑This is quoted from a past post (→here)
and is a Cyber Front front hub for rim brakes
with left and right tangent lacing,
but Extra Light seems very particular about
reversing the orientation of the hub shell,
and actually has instructions saying "put this side on the left."
For hooked-spoke hubs and
straight-pull radial-laced hubs,
orientation designation has no performance meaning,
but if the hub in the image above were Italian lacing or
reverse Italian lacing,
there would be meaning to the orientation specification.
In reality, it's reverse-JIS lacing
(interpreting the outer spoke as a J-spoke),
and even if the hub's left and right are swapped,
the relative positions of the spoke heads don't change,
so there is a performance-related reason
for specifying left and right.
With Light Bicycle rims,
I feel like OEM customers and users buying directly from the maker
often specify unmarked versions,
but this time the rim
had a logo applied with laser engraving.
