It is a Cannondale Scalpel with XX1 drivetrain.
I have a second option. This one is a new 2022 Scott Spark RC Comp. The Spark has 120mm travel f/r but weighs 28lbs. It is $4000.
But here is a catch. The Spark has an unknown delivery date. It could be anywhere between December and June. The Cannondale I can get now. I do not have a fs bike currently either.
I ride a 2018 scalpel. Its pretty good, overall, but I made a bit of alterations to make it more of a "Downcountry" bike. I added a dropper post and slacked the HTA by 1.5degrees to 68 degrees among other things. I love my rig and its tons of fun. HOWEVER, I would avoid the 2016. The HTA is a super steep 71 degree head angle!!! I have ridden them, and they are twitchy as all hell. Also the 100mm suspension on these bikes have a very hard tune (good for XC racing).
Another thing to consider is while the lefty shock are fantastic, the 2016 will require servicing and its expensive and you typically need to send it in (2mo wait without a fork). My bike has a RockShox SID fork which is a lot more manageable.
If what you are looking for is a super aggressive XC racer, this bike is a good option (although $3k is a bit steep). But dont be tempted by weight... my bike started at 24.5lbs and its sitting currently 27+ lbs with all my alterations.. and its much better for it! I compete in some light racing, but more or less enjoy my local trails. I wish I had a bit more squish, but its a great bike.
If it were me, I would spend my money on the Scott Spark, or keep looking.
