The Spinner® Chrono™ Power by Precor distances itself from the pack of indoor cycles that measure power by offering a hassle-free experience for riders, all while staying true to the iconic feel of a Spinner® bike. With direct power measurement, patent-pending magnetic resistance, and the brightest console back light in the industry -- with no batteries to change -- the Spinner Chrono Power bike will exceed expectations. It's all about Watts and direct power measurement. Precor raised the bar on accuracy and reliability by putting the strain gauge power sensor directly on the resistance system. The sensor is protected from shoes and sweat, and directly wired to the console to eliminate wireless pairing, manual calibration or the need for batteries.
