It's a Nitrous. Looks like they swapped out the shock for something else.
My advice is unless you're under 165lbs. and you're going to use this on race day only, look elsewhere. This is a super lightweight race frame. It was sub 5 lbs, which would definitely have an impact on long term durability. They are fantastic, no doubt, but I think it's not something you want to have if you don't want to replace a frame for a while.
I'm still wondering why they swapped the shock out.
