Another day of wheel... (and so on).
Before that, though.
During wartime, when metal resources were scarce,
there was an order torequisition donate
temple bells for collection,
but since bell towers that hang bells are structurally balanced
by the weight of the heavy bell,
if you remove the bell and leave it empty, the structure becomes vulnerable to earthquakes and strong winds,
so "substitute bronze bells" made of concrete would
sometimes be hung in their place.
Sometimes just natural stone with weight similar to the bell would be hung instead,
so it's not primarily about the bell's appearance—
rather, the balancing effect is what's being prioritized.
Long ago, there were high-end models of Soyo seamless tubular tires
that shipped
with the tire already mounted on a rim-shaped ring (with only a valve hole),
and even short of that,
with UV and friction protection covers placed on the tire,
tubular tires held in a circular shape on cardboard squares
with sides longer than the tire's diameter—
you can really feel the manufacturer's commitment to detail.
Anyway, another day of wheel... (and so on).
I've received several Shimano WH-RS300
rear hubs from customers before,
but this time I sourced one for the shop.
It's a 20-hole straight-pull spoke hub compatible with Shimano 11-speed,
but for some reason the shipping configuration is
abnormally heavy—it comes in an aluminum ring
with black flat wire pulling it tight.
Is this some kind of jig for properly setting the cup-and-cone ball bearings?
↑Surely they're not supplying something this heavy as an actual rim.
What's visible in the back is another identical aluminum ring
that was abandoned at my shop for different reasons.
The black wire itself—perhaps because its material composition is too far from stainless steel—
after being exposed to the outside air for about two years,
rust begins bubbling up from the inside.
Since the same thing doesn't happen with Sapim or DT spokes,
it's difficult to interpret this as being sport-grade spokes.
I built the rear wheel with an 88mm-high tubular rim
that a customer entrusted to me.
The customer said it was 80mm,
but the actual measurement is 88mm, and on the rim's outer edge
part of the part number reads "88T-25,"
which I believe means
"88mm height, tubular, 25mm width," so 88mm is definitely correct.
By the way, whenever an 88mm-high rim appears on this blog,
the post title is automatically forced to become "Eight-Eight."
I thought it had 24 holes,
but when I tried to build the wheel recently
it turned out to be 20 holes,
so I sourced a Shimano 20-hole rear hub—one that ships
in a frame with tension already applied to the flanges.
Shimano seems to have some particular commitment to
shipping this rear hub with tension applied to the flanges,
but I can't see any reason or benefit that outweighs
the downsides: disassembly being a hassle, everything besides the hub becoming waste,
and a significant portion of the shipping box volume being just air.
Campagnolo/CX Sprint, forced 2-cross lacing.
I'll do the spoke nipples later.
