Does anyone have a Ritchey WCS Compact Crank that could give a weight breakdown? Weight weenies doesn't have much (and nothing recent) and I'm very curious about the claimed weight of 570g for 2008. How optimistic is that?
How much do the chainrings weigh?

Thanks.

I'm not suggesting it's the lightest thing on the planet but light enough to to give it some consideration. Though I got one off ebay (few years old) and it's about 100g heavier than claimed which makes me wonder how optimistic the claim number is or if they have made huge improvements since then.

Dura-Ace Octalink BB 175g ~$50 (ebay new)
Ritchey WCS 570g ~$200
total: 745g ~$250

Dura Ace (not compact) (w BB): 740g ~$380
FSA K-force Light Compact (w BB): 660g ~$500

I have a set of the carbon ones. 565 grams w/rings.
The small ring is made of steel and is heavy; I replaced with an FSA 36 toother (vs the 34) and it cut 20 grams. I also replaced the large 50 toother with an FSA 52 and it added 25 grams. I didn't keep track of the ring weights; sorry. (I think 52x36 is a better compact range).
They are very nice cranks. Very stiff. However, I also got a chance to check out the IRD compact cranks. Better finish and 545 grams total.

Regarding Octalink-I have FSA Superlight cranks (515 grams with rings) plus the Dura Ace Octalink BB (175 grams) on my tri bike. 690 grams is pretty much lighter than anything affordable that's 10-speed. SRAM Red is 760 grams, Dura Ace is heavier.
Hopefully the new superlight FSA (I think that's 640 grams complete) will come down in price.
