Wheels again today (and so on).
I took in a WH-R8170-C36 rear wheel from a customer.
They wanted the hub replaced and the wheel rebuilt.
This is a different customer from yesterday's rear wheel.
Though yesterday's also ended up being a rear wheel after the rebuild.
It's gotten some use already.
That's actually nice.
Because then the customer can really tell the difference in how it performs.
I disassembled the wheel and pulled the nipple on the non-freewheel side completely off the rim without loosening anything.
The spokes are clearly long,
but the threaded section length is comparable to generic spokes.
It's not like Campagnolo's Bora spokes,
which have longer threaded sections.
I even checked the part of the nipple's inner diameter that has no threads
(the "periodontal pocket" area), and
at this rate the threads are pretty much fully utilized.
So if the spoke were to break at the beginning of the threads,
you could say the manufacturer bears some responsibility,
but that's not a manufacturer that would ever admit such a thing.
How much spoke thread protrudes past the nipple end face
varies quite a bit across the left and right sides on the C36 and C50, front and rear
(for example, on this rear wheel, the freewheel side is conservative),
and if those amounts were consistent,
you could think the manufacturer was following some philosophy,
but the front wheel has the same flange diameter on both sides
with a dish offset for the disc mount,
yet the spoke lengths are identical side to side,
so really it just comes down to the manufacturer being
way too casual about spoke length calculations.
It's built.
It's a Revo Disc Hub, 24-hole, black semi-comp, 46-spoke JIS lacing.
I'll do the truing later.
I'm reusing the nipples from the original wheel, but
while I recovered all the nipples from yesterday's rear wheel in reusable condition
and built it with DT's black aluminum nipples,
the decision of whether to use the original nipples or not is
something I keep to myself as professional know-how, so I won't write about it here.
If the actual wheel customer asks me, I'll tell them though.
