These are the Wizard NR100 frames. They retail for around $400 US. They’re UFS and are designed for 100mm wheels. They are machined out of a solid piece of aluminum, which makes them extremely solid but more expensive than other frames.

What makes the Wizard frames unique is their natural rocker. While most frame systems place the wheels in a straight line, or maybe offer an adjustable rocker system, the NR100 provide a unique rocker with no adjustments. This allows for more maneuverability than expected with such a long wheelbase.
