Built an Ambrosio Chrono 20 wheelset

Another wheel day (and so on...).

Built an Ambrosio Chrono 20 rim with a current-generation Record hub.
The rim shipment was delayed, but the hub shipment was even worse.

The rear wheel is 32H—I'd normally do a 48-spoke lacing pattern, but this is a low-profile rim so I can't.
Going with 46-spoke instead. Spokes are semi-competition.

Then I was about to build the front wheel, but something bothered me...
Relative to the direction the hub lettering reads, the ball-bearing adjustment nut is on the right side of the front hub,
whereas it's on the left side of the rear hub.

Didn't like it, so I pulled the axle and swapped left and right.

Front wheel's built too.

About that Atlanta rim wheelset from the other day—
I deliberately didn't post a front wheel photo here.
Campagnolo hubs prohibit radial lacing, so even though it was the customer's request,
if I post an image of that radially-laced front wheel, there are people who'll chime in about that.

↑The outer edge of the flange holes on Campagnolo Record hubs
is shaped so that outpoke spoke heads seat nicely.
