It is..a pair of Ryo Yabe Style Sundia Fly diabolos!
Pictured above are two red Ryo Yabe Style Sundia Fly diabolos. The carbon sticks are designed by Rich Munoz.
These diabolo have one-way axles 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 accelleration, and long spin runs.
It seems easier for me to do Vertax (Excalibur) moves with the Long-Bearing Sundias.
Unlike Superspins, Sundrias don't seem to loosen up.
They run much quieter than Spinabolos, but a little noisier than Superspins. Superspins are no longer available.
New are the Triple Bearing Fly diabolos & Monobolos.
