Petr Vabrousek, professional triathlete, "I do about half of my yearly cycling mileage on Powercranks – including the neverending winter indoor rides on my Computrainer. My spinscan numbers became almost perfect over a few months... It helped me not only to improve my bike splits, but also promoted strong running off the bike."

Tom Evans, professional triathlete, has been using his PowerCranks™ for over two-and-a-half years. When asked about any improvement from PowerCranks, he states plainly, "Just look at my results!" Tom's times have been dropping. "I think you can hold form longer... if you are keeping form, you are still moving well." Two days after our interview with Tom, he won Ironman Canada, setting a new bike Personal Record and a new course Personal Record.

Allie Lawler, professional triathlete, after about 6 months on her PowerCranks™, ran the Los Angeles Marathon as a training run (no taper) in preparation for Ironman California. She set a marathon Personal Record by 15 minutes.
