The 5-Bearing Axle is the most performant bearing of all. It spins faster than a triple bearing. This axle only fits to the EVO Hard cups. Exceptionnal stability, ultra smooth feeling and very quiet sound. You must try it to believe it. 

In 2020, Sundia improved the washer (see picture) to lock the axle strongly. It means that the diabolo is going to be tight for longer but it also means that the axle is very hard to remove once you assemble it on a diabolo.

Don't hesitate to contact us if you have questions regarding the assembly or if you want tips to remove the axle.
