Pioneer's full crankset power meters are simply some of the best power-monitoring systems on the planet, and Pioneer's Shimano Ultegra 6800 crankset is your chance to ride the same technology used by the world's best riders. Pioneer's created the first, and only, power meter that measures power output and pedaling stroke efficiency for each individual leg, in real time, so you can analyze and adjust your technique on the fly. At the heart of Pioneer's Power Meter System are two streamlined strain gauge monitors that can detect the slightest tangent and radial force direction as power's applied to the crank arms. This proprietary system detects the amount and direction of force at 12 different points in each pedaling stroke for each leg, allowing you to fine-tune your pedaling to find race-winning form. With advanced technology accurate to +/- 2%, ANT+ transmitting, active temperature compensation, Pioneer's power meter is perfect for any cyclist. Additionally, installation is fast, simple, and clean with zero wires, magnets, or zip ties. - Standard: 53/39 - Mid-Compact: 52/36 - Compact: 50/34
