"I began using Powercranks in 2001 as a rehab tool and after trying to resolve an Illiacus/Psoas strain that just would not heal and strengthen with regular rehab methods. I noticed significant improvements in pedaling mechanics, strength and power. I am convinced that Powercranks work and am glad I can recommend them to clients."

"From the angle of biomechanical leverage, the pedal stroke can be enhanced by focusing on hip flexion. Power Cranks do this very well. I recommend them to my clients who are interested in maximizing and maintaining efficiency."

John Howard, Coach US Cycling Hall of Fame member, Ironman Triathlon World Champion

"I started using the PowerCranks last year (2004) after trying them at an expo, my Ironman bike split (112 miles) went from 5:38 to 4:57 in one season as well as over 25 minutes off my marathon time. I recommend them to anyone who wants to improve their bike and run."
