This is the Black Knight Ion X-Force.
There are a few versions of this racket, and they have different specs.
Apparently the X-Force is made of Nano Crystalline Technology. Now crystals, they’re already pretty small. But Nano Crystals are EVEN SMALLER, so that must be good, right? To their credit, Black Knight actually explains on their Website that this is “an additive incorporated into the carbon fibre that not only helps reduce vibration but binds the fibres for added durability.”
Here’s what Paul from PDH Sports had to say about the yellow and black versions:
