History / About
Released in 2010 to commemorate the original SpinFaKtor’s tenth anniversary, the SFX (SpinFaKtorX) takes a new direction: instead of outer metal rings, it places an aluminum alloy weight ring in the midship position for a balance between control and stability. The new Solid Spin Axle system improves reliability. Available with both a standard bearing (responsive) and an included Speed bearing (unresponsive).
