FSOT: Quarq Riken 172.5 BB30 53/39

Hey ya’lls,

Due to the realization that most of my racing this year will be steep stuff on a road bike, I want to swap my Quarq for a compact.

I HAVE:
Quarq Riken 10R (Omnical)
172.5mm arms
SRAM Powerglide Black Chainrings (So hot right now)
BB30
53/ 39 chainrings / 130 bcd.
Extremely stable offset - consistently in the single digits.

WANT:
Quarq Riken, not abused
172.5 mm arms
PREFERABLY 52 / 36 chainrings but will also take 50/34 chainrings. (Bonus for both)
BB30 or GXP (bonus for adaptors)

Or, for sale for $1100 shipped and paypalled (CONUS).
