I rebuilt the front wheel from JIS lacing to Italian lacing.
Today it's wheels again (and so on).
I built my friend's rear wheel.
The hub is HB-7710, the same as the front wheel,
and since it's a rear hub it's HB-7710-R.
Just like the front hub, there's no
Dura-Ace marking on the hub shell,
but since it's 36 spoke holes there is an NJS stamp,
which I'll use as the basis for determining left and right
(making the right side of the image above the right side).
It's a dual-sided hub, but the customer wanted Italian lacing.
The front hub had traces of reverse JIS lacing,
but this hub was laced JIS style.
On the Mavic rim, where the joint was welded and then finished with machining,
the inner side of the rim has a sticker to hide the step,
and to not make the reason obvious,
there are ETRTO and country of manufacture markings, but
On this Open Pro rim,
one of the symmetrical stickers
hides the joint, so
the exact midpoint between the two stickers
is not the phase opposite the valve hole.
In the image above, directly below the tire illustration
on the left sticker is the phase opposite the valve,
where the rim joint is.
So when I align the valve hole phase with the already-built front wheel,
there are cases where the sticker positions don't line up,
and cases where they do.
For the front wheel rim, I determined left and right based on
"the side where the serial number sticker on the outer rim
reads correctly is the right side,"
but for the rear wheel rim orientation,
I decided on "align the sticker position with the front wheel."
So whether the outer sticker orientation on the rear wheel rim
matches the front wheel is uncertain, but
this time they matched too.
What surprised me more was that these two rims,
true to the meaning of their serial numbers,
were in completely consecutive sequence.
Amazing.
It's built.
HB-7710-R 36 hole
All Competition 88 Italian lacing.
I'll do the wire tying later.
For the front wheel, I decided it wasn't necessary so I didn't do it.
