FSA SL-K compact carbon crankset, 172.5mm crankarm length, 50/34 chainrings, plus another set of 50/34 chainrings, $75 shipped to lower 48.
Please note the self-extracting crankbolt is getting a bit worn (see pic). It still holds a bite on the allen wrench, but it should be replaced. You can get them new online for $8.45 (http://www.cycleclubsports.com/p-21935-fsa-self-extracting-left-crank-arm-bolt-for-carbon-mega-exo-road-cranks.aspx).
I selling it because I upgraded my bike to a SRAM Red crankset and no longer have use for this one.
