Achieve your training goals: the INPower DM Road Crank with Rotor Spidering
Integrated power measurement technology lies at the heart of the Rotor INPower direct mount road crank. Power measurement data is taken from the left leg using strain gauges in the axle, which provide precise values for power, cadence, torque efficiency and concentricity. All internal electronics are waterproof, which centres the rotating mass and provides maximum protection.
The Rotor InPower DM road crank is a powerful tool that allows you to measure individual pedalling biomechanics using the Rotor Power App. Get real-time access to specific information such as Torque 360, Optimum Chainring Angle (OCA) or a recommendation for the optimal chainring position (OCP).
Connect your Rotor INPower DM crank to a bike computer or smartphone via Bluetooth Smart or ANT+ to easily export your data and dive deeper into training analysis with platforms such as Trainingpeaks.
Setup and calibration are user-friendly, and everything is powered by a standard AA battery in watertight casing, which provides up to 300 hours of operation.
This bundle is supplied with an oval Rotor Spidering double chainring (Q-ring), and it is manufactured in one piece and can be directly mounted on the axle without tools. Only a 10 mm hex tool is required to mount or dismount the crank arm on the drivetrain side. Crackling from the screw connections between spider and chainring is now a thing of the past. For the first time, the direct mount system facilitates the fine adjustment of oval chainrings in 1-degree increments, which helps to create unique customisation options tailored to individual requirements.

Technology:
Aluminium CNC
Computer Numerical Control (CNC) milling ensures a precise and uniform production process. This is particularly important when manufacturing components that must function properly and work in congruity with other parts. Thanks to state-of-the-art CNC equipment, Rotor parts are manufactured with extreme precision, down to a hundredth of a millimetre.
TDS
Rotor CNC cranks are stiffer than competitive cranksets thanks to Trinity Drilling System (TDS). In this procedure, three full holes are drilled from the bottom bracket to the pedal. This creates a box-like grid, similar to a box girder bridge. This makes the cranks extremely stiff while at the same time reducing weight, resulting in an excellent stiffness-to-weight ratio.
INPower
Inner values count! The technology of the Rotor INPower is completely and securely positioned inside of the axle. The patented ROTOR INPower with integrated power measurement will improve your training in both quality and experience aspects. It is one of the lightest integrated power measuring cranks and is an>
OCP
Optimum Chainring Position (OCP) indicates the various adjustments that Rotor Q-Rings offer to adapt to the rider’s specific pedalling characteristics. Q-Rings have up to 5 OCPs. These positions help to optimise your pedalling behaviour.
You can determine your OCP if you know your optimal chainring angle (OCA), which you can determine by a Torque 360 step analysis with the user software of Rotor 2INPower and INPower.
