To celebrate the 10 year anniversary of SpinFaKtor, this is the SpinFaKtorX. At a glance, it's hard to see the family resemblance. The name really comes from a different place; the original was the first to come loaded with a metal rim, ushering a new standard for YoYoJam. It's only appropriate that the new SpinFaKtor would do the same.

At first sight, it's clear that this is a new direction for YoYoJam. The midship weight and the incorporation of the Solid Spin Axle system. These two systems make their debut in the SFX, and it looks very solid indeed. Until now, the metal outer ring has ben one of YoYoJam's most recognizable design features, delivering impressive spin, but rather than conforming to their own conventions, they've dared to try something new. Instead of the weight in the outer rim, it's in the body in the form of the midship weight, giving a balance between control and stability. This is an impressive example of things to come from YoYoJam.
