You can fast forward to 4:00 for a close up of it...

Something similar to a Powerdome cassette but not available yet?

Not sure who makes it (looks like a machined XTR) but I know I wouldn't ride it. That thing would fold in a few pedal strokes.

Well that's what I was thinking too, a machined XTR (aside from the odd coloured, possibly 36t ring) but why? The rest of the bike's build isn't particularly weight-weenie'ish so why put the work into the cassette? The only thing I can think of is its NAHBS and they just wanted to add some more wow factor for the show.

It looks like someone got a little carried away machining an XX cassette, as you can still see the aluminum cog through the rest of it. But like Rivet said, it'd probably fold in a second, even if it is steel.

That's funny, I was thinking those exact things, It just doesn't add up? The 36t could be an FRM but it almost looks hand made.

Hmm I think you're right. I can defintiely see those distinct arms of the 36t xx ring through the massive holes drilled in the rest of it. Also the "powered by sram" sticker is probably a hint.

Maybe the 36t is black anodized like the rest of the XO group on the bike?

The SRAM big cogs are ano'd a dark grey on these types of cassettes in 9 speed.

In my opinion this is that cassette:

SRAM XG-1080 10sp X Dome Glide Cassette:
