Rotor 2INPower DM Road Power Meter Cranks

Uncover your strengths, work through your weaknesses: the 2INPower DM Power Meter Crank from Rotor

Integrated power measurement technology is the basic principle of the Rotor 2INPower DM crank, which precisely measures the power output of both your legs. Get a better picture of your unique biomechanics and discover areas where you can improve your pedalling technique.
When it comes to improving performance, accurate power measurement and pedal optimisation are absolutely crucial.

Power meter technology at the heart of the 2INPower DM crank gives you the precise and comprehensive data you need to improve your output. Using 4 sets of opposing gauges, the power of the left and right leg is measured independently of one another, and paints a clearer picture of your pedal stroke balance, power, cadence and torque efficiency. Get real-time access to specific information such as Torque 360, Optimum Chainring Angle (OCA) or a recommendation for the optimal chainring position (OCP).
Use this technology in conjunction with oval Rotor Q-Rings to adjust your OCP in one of 5 possible positions, so that you tune your pedalling efficiency and maximise power transfer for every revolution.

Connect your Rotor 2INPower crank to a bike computer or smartphone via Bluetooth Smart or ANT+ to easily export your data. Dive deeper into training analysis with platforms such as Trainingpeaks.com.
Direct mount technology includes of a clever spline interface between the crank arm and chainring, which guarantees exceptional rigidity and direct transmission of pedal torque.
It goes without saying that setup and calibration are user-friendly, as is the battery with up to 250 hours running time that can be recharged via a magnetic plug.

Technology:

Aluminium 7055
Rotor uses only the best materials to make the best cranks. 7055 combines the superior physical properties of a 7000 alloy with incredible wear resistance. Each bar of raw material is ultrasonically inspected to ensure that it is free from internal defects.

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.

Twin Leg
Rotor's Twin Leg Concept (TLC) offers the stiffest possible crankset by balancing the left-right stiffness of the cranks. A super stiff right crank arm is of little use if the left crank arm cannot keep up. By designing the pedal cranks as a set instead of two separate crank arms, TLC contributes to the best balanced cranks available.

2INPower
This crankset is based on the well-known Rotor INPower wattmeter system. The 2INPower measures the power of each leg individually, providing accurate balance and performance data and uncovering areas for improving pedalling performance. The power measurement of the left leg is typically measured in the axle via two pairs of opposing gauges. Two pairs of additional opposing gauges are placed in the right crank arm, which measure the power of the right leg only. Independent or combined analysis utilising Optimum Chainring Angle (OCA) and Torque 360 metrics can be performed with the free user software.

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 (Road) or up to 3 OCPs (MTB). 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.
