Product Description
The INPEAK Shimano Ultegra R8100 Powercrank-E - Single is a single-sided power meter with a rechargeable battery, precise ±2% accuracy, and seamless ANT+ and Bluetooth data transmission. It integrates directly into the Shimano Ultegra FC-R8100 crank for a clean fit, low weight, and consistent performance. The sealed IP67 housing and active temperature compensation ensure reliable readings in all conditions. It delivers power, cadence, and advanced cycling dynamics data for structured training and performance tracking.Key Features and Benefits:Single-sided power meter integration: The power meter is built directly into the Shimano Ultegra FC-R8100 crank arm, which removes the need for external sensors or complex setups. This keeps your drivetrain clean and reduces installation time. The outcome is a simple, reliable system that works without added components.Rechargeable Li-Po battery system: The internal 110 mAh battery charges via a magnetic USB cable, removing the need for coin cell replacements. This lowers long-term running costs and reduces maintenance. The result is consistent power delivery with up to 90 hours of ride time per charge.High measurement accuracy (±2%): The system delivers precise power data across a wide range of 20-2000 watts. This level of accuracy supports structured training and performance analysis. The outcome is dependable data you can use to track progress and adjust effort.ANT+ and Bluetooth connectivity: Dual transmission protocols allow the power meter to connect with a wide range of head units, apps, and training platforms. This ensures compatibility with most modern devices. The result is easy data access across your preferred training ecosystem.Active temperature compensation (ATC): The system adjusts automatically to temperature changes between -5°C and +50°C. This prevents drift in power readings caused by environmental shifts. The outcome is stable and accurate data in all riding conditions.Advanced cycling dynamics data: Built-in sensors track cadence, torque effectiveness, pedal smoothness, and left/right balance via TWiN2 metrics. This gives deeper insight into pedalling efficiency. The result is improved technique and more effective training sessions.Durable and waterproof IP67 housing: The sealed unit protects internal electronics from water, dust, and road debris. This extends the lifespan of the device under regular use. The outcome is consistent performance in wet and harsh conditions.Lightweight low-profile design: The power meter adds only 10 grams to the crank arm and maintains a compact shape. This avoids affecting pedalling dynamics or bike weight. The result is accurate measurement without compromising ride feel.Consistent and accurate power data is essential for structured training and performance tracking. The integrated design, precise measurement system, and stable temperature compensation work together to deliver reliable outputs across every ride. With advanced metrics and long battery life, it supports ongoing analysis without adding complexity to your setup.For riders who want clear data and a straightforward system, this power meter offers a practical solution. Its integration, durability, and accuracy make it a dependable choice for regular training and performance monitoring.Specification:Measurement precision: ± 2% Power measurement range: 20-2000 W Cadence range: 20-200 rpm Weight: 10 g (INPEAK device) Case tightness: IP67 Manual zero-offset calibration: Yes Temperature compensation: Yes Gyroscope + Accelerometer: Yes Torque Effectiveness: Yes Pedal Smoothness: Yes Cycling Dynamics: Yes (TWiN2) Balance L/R: Yes (TWiN2) Operating temperature: from -5°C to +50°C Storage temperature: from -20°C to +50°C Battery specificationsBattery type: Li-Po, rechargeableBattery capacity: 110 mAh Battery autonomy in use: max. 90 hours Battery autonomy in sleep: max. 6 months Battery autonomy in ShipMode: max. 24 months Charging time (0% -> 100%): 2 hours Low battery notification: Yes Battery charging temperature: from +5°C to +40°C Battery lifetime: Less than 20% capacity loss after 300 full cycles.
