It is..a pair of Kickfire Super Nova diabolos!
Pictured above are two Kickfire Super Nova diabolos. The sticks also come from Kickfire.com.
These diabolo have one-way axles
with triple bearings
that run smooth, fast, and quietly. The axle is flared outward to match
the taper of the cups (bells) on each side. This is truly an easy diabolo to run and hand & finger grinds are quite easy to do.
As with all one-way axles the Climb the String is not possible, yet the gains of the axle are immense; including quick
acceleration, long spin runs, and recoveries after drops.
Many diaboloist use diabolos with bearing to do Vertax (Excalibur) diaboloing where the diabolo is vertical.
This diabolo similar to the the Juggle Dream Hurricane, but the Super Nova has softer cups and are a bit heavier.
There is room on the axle to add a spin-on LED light kit. The translucent cups would make this an excellent light up diabolo.
Kickfire Diabolos sell two other fixed axle models as well, the Nova and the Comet. Comet for beginners, Nova for anyone.
