Does this setup work with the new Sram Red Yaw FD or do you need to use the older FD?

Great, thanks. A side question, did you just use grease on the chainring bolts, or some kind of locktite?

Locktite!

I don't understand how to install the chainring bolt that's hidden behind the arm. I have the Extralite chainring bolts and it doesn't reach the threads in the arm. There's also nothing between the two rings. Are they just suppose to float like that? Do I need a special bolt?

You need the bolt and spacer that came with the Red crank.

I see. Damn. I found just the arms on eBay, so they didn't come with it. Do you know if I can purchase it from somewhere?

This is the Sram part number for the chainring bolts and spacer for the hidden 5th bolt cranks: 11.6918.000.001 I do not think you can buy just the spacer and the one bolt individually. They are available all over the web.

Has anyone run the new Extralite RC2 rings? I'm thinking about getting a set from Fairwheels and I've been hearing rumors of dripping flex.
I've been running Praxis rings for the last year and love them.
Just want the minimal look and 94g 50/34 weight!!

I'm running them and I don't notice any flex and I'm 200lbs. They've been great, and are really well made.

Swooped a set of Lightning Compact cranks and purchased RC2 rings.
So light, even with BB30 BB. 560g complete.
The pic was before I moved the rings around.
Does anyone know where I'm supposed to put the included pin? They usually hide behind the crank arm.
