What... what are these things...!?
Anyway, another wheel build today (and so on...).

A package specified for September 19th delivery arrived at our shop on September 18th.

I received WR hubs from a customer.
Both front and rear are 28H.

The flange holes on the front hub are drilled quite close to the inner circumference.
They've clearly put thought into managing the load on radial lacing.

The rim is an Ambrosio Formula Chrono 20.
Both are 28H as well.

The sticker is the same as before, but

the laser-engraved manufacturer logo looks like half-width characters—
this is the first time I've seen that.

Built!

Front wheel is black CX-RAY inpoke radial laced.

For the rear wheel, 48-spoke lacing wasn't possible, so I went with 46-spoke.
Spokes are black half-comp.
The customer didn't request spoke nipple ties, but
over the course of the past year we've gained the capability to do black ties,
so I'm thinking of suggesting it.

I say "the past year" because
that September 19th delivery date mentioned earlier
was September 19th, 2013.

For the nipples, per customer request, I used gold aluminum nipples on both sides of the valve, and black aluminum nipples for the rest.

There was a slight gap at the rim seam, but once I tensioned the spokes, it closed right up.
All's well that ends well.
