For a relatively new invention, PowerCranks™ have gained a remarkable acceptance among amateur and elite athletes across a broad spectrum of sports. Many cyclists and triathletes have done their own tests, using either wattage meters on their bicycles or running times to show their dramatic improvements from PowerCranks™.

Athletes under the pressure of competition are a fantastic proving ground, and in that laboratory, PowerCranks™ are definitely a success. Check out the coaches pages to see what many sports science experts believe.
