By integrating performance measurement technology as the core of the crank design, the INpower DM MTB accurately captures your power, pedal stroke, cadence, and torque effectiveness to enhance your performance regardless of the terrain. The INpower MTB technology is housed within the axle, where it is protected from stones, impacts, falls, and contaminants such as mud, sand, and clay. Track your ride with real-time data, including proprietary metrics like TORQUE 360, optimal chainring angle (OCA), and a recommendation for your optimal chainring position (OCP). Combine this key information with Q-Rings oval chainrings to customize your OCP. Connect via Bluetooth or ANT+ to your bike computer or smartphone to gain a comprehensive view of your pedaling performance through analysis platforms. In conjunction with the free Rotor Power smartphone app, you can access relevant metrics and graphs that were previously only available in biomechanical training labs.
