250Hz NSD PowerBall - Speed demon

Still the fastest gryo on the planet*, the 250Hz range has been certified to 15,000rpm but will clock well in excess of 16k in the right hands these days, such is the precision of balance on that 250Hz rotor.

250Hz balls are available with an inbuilt digital speed meter (termed: 250Hz Pro) or without (termed: 250Hz Classic) - the counter can be added at a later stage if required.
