Product Description
The INPEAK Shimano Ultegra R8100 Powercrank - Single is a single-sided power meter with integrated Ultegra FC-R8100 crank that delivers accurate power data, long battery life, and reliable performance in all conditions. It uses ANT+ and Bluetooth to transmit power, cadence, and advanced cycling data. The system is individually calibrated for precision and built with a sealed, impact-resistant housing for consistent use across road, gravel, and MTB riding.Key Features and Benefits:Single-sided power meter integration: The power sensor is built directly into the Shimano Ultegra FC-R8100 crank arm, which ensures accurate force measurement at the source without adding external components. This improves reliability and maintains a clean drivetrain setup, resulting in consistent data with no setup complexity±2% measurement accuracy: Each unit is individually calibrated to deliver highly precise power readings across a wide range of outputs. This level of accuracy supports structured training and performance tracking, giving you dependable data for making informed adjustmentsANT+ and Bluetooth connectivity: Dual transmission protocols allow seamless connection to bike computers, smartphones, and training apps. This ensures stable data transfer across multiple platforms, so you can track and analyse performance without signal dropoutsActive temperature compensation (ATC): The system automatically adjusts for temperature changes between -5°C and +50°C to maintain consistent readings. This prevents data drift in varying conditions, ensuring reliable output whether riding in cold mornings or warm conditionsWide measurement range (20-2000W): The system captures both low-effort riding and high-power sprint efforts with equal accuracy. This allows full performance tracking across all riding styles, from endurance training to peak output effortsAdvanced cycling dynamics (TWiN2): Metrics such as pedal smoothness, torque effectiveness, and left/right balance provide deeper insight into pedalling efficiency. This helps identify inefficiencies and supports targeted improvements in technique and power deliveryIP67-rated waterproof and impact-resistant housing: The sealed casing protects internal components from water, dust, and impacts. This ensures long-term durability and consistent operation in harsh riding conditions, including wet roads and off-road useCR2032 battery with up to 200-hour runtime: The widely available battery provides long usage between replacements and supports extended training blocks. This reduces maintenance interruptions and keeps the system ready for regular useConsistent and accurate power data allows you to track effort, control pacing, and measure progress over time. The integrated design ensures stable readings without added components, while advanced metrics provide deeper insight into pedalling efficiency. This supports structured training and helps refine performance with reliable, repeatable data.This power meter combines precision, durability, and ease of use in a single integrated system. It gives you the data needed to train with purpose and track improvements with confidence. A practical upgrade for riders who want accurate performance feedback from every ride.Specification:Measurement precision: ± 2% Power measurement range: 20-2000 W Cadence range: 20-200 rpm Weight: 10g (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 specifications:Battery type: Lithium CR2032 3V Battery capacity: 200 mAh Battery autonomy in use: max. 200 hours Battery autonomy in sleep: max. 6 months Battery autonomy in ShipMode: max. 24 months Low battery notification: Yes Software specifications:Software update from INPEAK MANAGER App: Yes Modification of “Scale Factor”: Yes Zwift Compatible Mode: Yes ANT+ Compatibility: Yes Bluetooth Low Energy Compatibility: Yes Auto sleep: Yes Auto wake-up: Yes Package contents:Crank with integrated power meterBrief instruction manualSticker setSpare O-RingDevice data card1x CR2032 battery
