A customer left a Cosmic Carbon (high-end carbon wheelset) with me for service.

The "SSC" designation after Cosmic Carbon indicates the second generation,
but the front wheel specs are the same as the first generation.
Both the first generation and early second generation models had 16-hole rear wheels,
but once they realized it was risky,
they switched to 20-hole rims from the late second generation onward.
This one's rear wheel should have been 16-hole.

There's a chronic buildup mark from rim cement in the braking zone,
so I was about to say
"This must be a front wheel being used as a track wheel,"
but just as I started saying
"There's rim cement in the braking zone,"
the customer beat me to it: "Oh, that's for track use."
Cosmic Carbon from this era should have double-eyelet construction,
but since this is a tubular rim, the manufacturing process must differ—it has single eyelets.

↑One spoke was bent, and there was quite a bit of lateral runout.

Fixed.

While working on it, I found another bent spoke
and replaced that one too.

↑I noticed it because the spoke's paint was flaking,

but under tension it was almost perfectly straight,
so I might have overlooked it if these were silver spokes.
