Integrated Power Measurement for Structured Road Training

Overview

The Rotor Inpower 3D30 BCD110x5x2 Crankarm Assembly features a power meter housed inside the crank axle. This protected position helps measure left-leg power while shielding the electronics from impacts and external contamination.

Detailed Pedalling Analysis: The system records power and cadence while supporting Rotor metrics such as Torque 360 and Optimum Chainring Angle. These insights help riders understand power delivery and refine their pedalling technique.

Durable 3D Construction: The machined aluminium crankarm provides the stiffness required for efficient power transfer during climbs, intervals and sustained road efforts. Its 170 mm length offers a familiar fit for performance road setups.

Five-Bolt Road Compatibility: A 110 mm five-bolt spider interface supports compatible double road chainrings, including suitable round rings and Q Rings. The 30 mm axle works with compatible Rotor bottom brackets across several frame standards.

Rotor Inpower 3D30 BCD110x5x2 Crankarm Assembly combines protected power measurement, detailed ride metrics and dependable road performance.

Features
  • INpower: Measures left-leg power through strain gauges positioned inside the crank spindle.
  • Integrated Spindle Electronics: Protected internal placement improves resistance to impacts and weather.
  • Real-Time Training Data: Transmits power, cadence and pedalling metrics to compatible devices.
  • Long Battery Runtime: Uses a replaceable AA battery for extended riding periods.
