I have a 56cm Aethos Expert (msrp - $5500) w/ a couple of upgrades, taking it almost to the Aethos Pro (msrp - $7500) level.  The stock bike came with SRAM Rival shifters/brakes, front and rear derailleur, and a 172.5 mm Rival crankset (the one w/ the powermeter in the spindle).  Specialized describes the color as Satin Metallic Deep Lake.  It's blue (ish).

I swapped out the stock cranks for 165 mm SRAM Force carbon fiber cranks with 35/48 rings, and swapped out both derailleurs for Force derailleurs, and swapped the stock tires for Conti 5000 S TR, 28mm, set up tubeless.  

I purchased the bike directly from Specialized in July of '24 and according to the data in my TrainingPeaks files, I've ridden it a whopping 30 times over 14 months for a total of 1268 miles.  

Asking $4200 as described, or $4600 including an AXS Red/Force powermeter.  I can ship at buyer's expense, or will deliver within a few hours of Albuquerque.
