HOW MUCH FORCE / RESISTANCE / TORQUE DO THE METAL SERIES POWERBALLS GENERATE?

The Titan Pro generates 22.7kg/ 50lbs at 10,000rpm and the Diablo Evo generates 18.7kg/ 41lbs at 10,000rpm. 10,000rpm is an achievable spin speed for the average person. As your wrist, grip and forearm strength increases, your spin speed will become faster and you will be able to generate more resistance. While the metal series are calibrated to spin up to 20,000rpm, no human would have the grip strength to generate this type of speed. Theoretically, these products can generate over 40kgs / 100lbs but even the very strongest of athletes may only manage to generate max. 28kgs/ 60lbs. We look forward to someone going faster!
