A customer left me a Cosmic Carbon Pro UST for service.
The missing "SL" isn't a typo—this is a different model from the SL UST.
There are two wheels because the customer bought them together for a friend as well.
The manufacturer's suggested retail price is ¥220,000 (excluding tax),
but apparently they found a place selling them for under ¥80,000 with tax included, so that's where they bought them.
Both the front wheels are perfectly centered,
and the rear wheel's center offset was minor enough to correct while truing the rim,
so overall these are pretty decent for Mavic stock wheels.
The spokes are square aero profile with distinct edges,
unlike the SL's elliptical aero spokes that could practically cut your fingers.
The cosmetic spoke markings don't have the "SL" designation either.
The hub uses an FTS-L freebody rather than Instant Drive 360,
but after an overhaul, this one maintains its initial performance
(or more accurately, the ratchet mechanism's condition) for longer.
They switched to Instant Drive 360 because the bearing bore diameter prevents
converting to thru-axle compatibility, but for overall performance
when used with quick-release hubs, I personally think this one's the better choice.
