If I didn't already have a current-era high-spec' bike (Colnago CX-Zero, SRAM Force22/Red22 gruppo), I'd lay down the $$$$ for an Argon18 Krypton/Ultegra gruppo. 'Cause, you know, it's Mika-chan, an'at.
Seriously (and, once again), STUPENDOUS detail on the bike. Hitomi Kazuya is doing God-level work on these illustrations.
