CompuTrainer provides the most interesting indoor bike experience yet created. It increases your cycling power by 20 to 30% and your speed by 2 to 4 MPH. Whatever your starting point, you’ll improve significantly. CompuTrainer is best in its class by a wide margin. It sets the industry standard for accuracy (± 2.5%), power (1500 watts), quality, and service lifetime (10+ years). Exclusive performance features like SpinScan™ electronic pedal stroke analysis and Adjustable Aerodynamic Drag Factor are unique to CompuTrainer. Cycling and triathlon coaches worldwide use CompuTrainer as their primary testing instrument. USA Triathlon, USA Cycling, and the Canadian Cycling Association test and train their team athletes with CompuTrainer. You'll be amazed at the realism of CompuTrainer's 3D interactive graphics. Rolling Green Hills or Painted Desert Scenery, curves, split screens, and panoramic helicopter views combine with advanced computer algorithms to create the true "feel of the road". Real time representation of essential data such as power output, heartrate, current speed, real-time & average values are given. SpinScan Pedal Stroke Analyzer is an exclusive CompuTrainer feature that helps you increase power and efficiency. The multicolor torque graph represents one full 360 revolution divided into 15 segments. The left /right leg percentage power splits give you the feedback needed to pedal in "circles". It will identify "flat" or "dead" spots in the pedal stoke where optimal power is not transferred to the drive train. CompuTrainer is more than a premier bike trainer. It's also a precision bicycle ergometer measuring wattage, heartrate, and cadence, which matches ergometers like the Lode and SRM costing much more.
