Another day of wheel building (and so on).
A customer entrusted me with two
50mm deep, ETRTO 451mm rims with UD carbon finish.
Both are 32H, and I'm building front and rear wheels for rim brakes with these,
but in combinations like this,
if one of them happens to be an offset rim,
you might not notice and end up building the rear wheel first with a non-offset rim,
which leads to a real mess.
I built the front wheel first for reasons other than that concern,
but I am checking whether just one of them might be an offset rim.
There doesn't appear to be any clear difference
in left-right hole offset on the rim holes,
but there are instructions for the direction of the freebody when building the rear wheel.
That said, if there really were a clear hole offset,
it wouldn't be wise to forcibly build a rim brake front wheel.
Even though I think there's no apparent difference in hole offset,
when building the rear wheel, I follow the instructions
unless there's a solid reason to go against them.
It's built.
Mystery hub, 32H, #14 black Champion spokes, reverse radial lacing.
Initially I told the customer I'd build it with #15 plain spokes,
and I actually did a trial build with #15 plain twice,
but something didn't look quite right, so I asked the customer's permission
and switched to #14 spokes.
Just to be clear, I didn't charge the customer for the parts I made mistakes on.
The hub has slots cut into it,
accommodating flat spokes 2.3mm wide or larger.
I don't know which manufacturer makes this hub, but
the 5mm Allen key socket chamfering and
the serrated end detail are remarkably similar to hollow axle bolts on
another hub—different in diameter and hole count,
but with remarkably similar flange taper characteristics—
a hub with the same machining pattern on the hub body
that makes the reflections of my camera's six lights look identical.
I have a hunch about which hub that might be.
