Is power measurement too scientific and overly complicated? Are watt values only one of many confusing numbers on the very full display of the bike computer?
ROTOR wants to prove the opposite with the 2INpower Road DM Powermeter and the ROTOR POWER analytics software. The crank-based powermeter helps you achieve bigger successes, as it allows for performance-oriented training thanks to easy handling. This is a considerable advantage over heart rate based training, since power in watts is not subject to any fluctuations in temperature, altitude or numerous individual influences like your form of the day or stress. Therefore, the measured values are extremely precise and comparable.
The ROTOR 2INpower Road watt measurement crank measures the wattage you have provided using a combined strain gauge system in the crank axis and right crank arm on both sides, measuring the left and right leg independently of each other. This has the invaluable advantage of analysing the differences between the right and left leg, recognizing imbalances and allowing you to work on them directly. Moreover, the crank delivers accurate data on cadence, pedalling efficiency as well as on power and torque efficiency. The high-quality measuring equipment is placed inside the axle and in the right-hand crank arm, so that it is visually integrated as well as well-protected. There is no need for expensive maintenance or battery replacements in the workshop. The integrated lithium-ion battery may be charged via USB cable and offers enough power for approx. 250 hours of training.
When used in combination with the included oval, Direct Mount Q-Rings by ROTOR, the 2INpower Road DM crankset achieves maximum performance for even more efficiency and comfort. The ROTOR POWER analysis software allows you to individually adjust the chainring position with the to best suit your personal preferences (OCP=optimal chainring position), so you can use your power more effectively and relieve your muscles and joints. A simple solution to help you increase speed!

All current ROTOR cranks of the Road Series ALDHU and VEGAST, the MTB series RHAWK , RRAPTOR and KAPIC as well as the powermeters INpower DM and 2INpower DM use the established Direct Mount system for chainring installation. A system that has proven its worth in mountain biking for years. This allows for easy chainring replacement, direct engagement on the axle and maximum flexibility in the choice of gear ratios and drivetrain characteristics. Moreover, the fine toothing between crank and chainring allows you to adjust the oval ROTOR Q-rings to within 1° of accuracy.
The cranks are compatible with classic round or oval chainrings for single or double drive units with the ROTOR one-piece design. The optimal Direct Mount spider gives you the option of using further spider-based chainrings.
ROTOR POWER analytics software:
All ROTOR powermeters let you simply analyse your cadence using the free ROTOR POWER analytics software for computers (available for Windows/Mac download on the ROTOR homepage) as well as the app for smartphones or tablets (available in the App Store for iOS or Google Play Store for Android). The software also lets you alignment and visualization of the oval ROTOR Q-Rings and chart the power distribution of a 360° rotation. For rapid and simple efficiency optimisation.
Different leg lengths, a crooked hip or just differently pronounced leg muscles often lead to left-right deviations. This is perfectly normal and common. The balance value allows you to get information about the percentage distribution and to optimize the your pedalling so that both legs each perform approx. 50%.
This feature shows you how smoothly you are pedalling. It is the ratio between the average and highest power per pedal stroke, measured in percentages.
OCA "Optimal Chainring Angle":
This feature lets you determine at which angle of the crank arm you are using the most force. Especially when used with oval chainrings, this lets you very quickly determine the optimal chainring position.
OCP "Optimal Chainring Position":
The optimal chainring position is very important for oval chainrings. OCP stands for the various setup positions that the ROTOR Q-Rings offers in order to adjust to a rider’s specific pedalling style. You can determine your OCP if you know your optimal chainring angle (OCA), which you can find out using the TORQUE 360 pedal analysis with the ROTOR POWER analytics software. The OCP is only available in connection with ROTOR Q-Rings.
The INpower technology can chart the torque applied to the pedals and visualises the distribution of power in a pedal revolution from all angles.
The ROTOR INpower technology doesn’t combine the power measurement of both legs, but instead measures each individually. So you can analyse the full pedal revolution and determine how forces are applied on the down-stroke (positive) as well as up-stroke (usually a negative value).
The TORQUE 360 graph is helpful for learning your individual pedalling pattern and for improving your pedalling technique.
Functional Threshold Power (FTP):
The Functional Threshold Power (FTP) is an important value for analytics. This shows how much power you can maintain over one hour without getting exhausted. It is uses a 20 minute FTP test to determine the values and derive the areas for training. This allows you to significantly improve the management of your training. Knowing your FTP value is also helpful for competitions and long ascents, so you don’t overpace and can better distribute your strength. Helping you get to the top faster or be further ahead in the race.
