ROTOR manufactures complete crankset power meters for the road, MTB and track. They offer the 2INpower DM which measures independent left and right leg power as well as the single-sided INpower DM. ROTOR power meters feature direct mount chainrings, dual ANT+ and Bluetooth SMART and are optimized for Q-Rings.

Additional Information:

Installation is pretty straightforward assuming you have insured compatibility with your current bike frame. They are equipped with the UBB30 axle system, which makes their power meters compatible with almost all standard frames in the market when used with the correct bottom bracket.

ROTOR power meters weigh around 500-750 grams depending on the model. When considering weight, be sure to focus on added weight by taking into account the weight of the crankset you are replacing.

Power Measurement
The ROTOR 2INpower measures power from both legs in addition to providing independent left/right power. The INpower cranks measure left leg power only and, like other left side power meters, double the value to calculate total power.

The ROTOR 2INpower features rechargeable batteries with approximately 250 hours of battery life. The ROTOR INpower units use AA batteries with approximately 300 hours of battery life.

Communication Protocol
The power meters transmit data via both the ANT+ and Bluetooth SMART wireless protocols. This means they are compatible with any bicycle computer, smart phone or tablet.

ROTOR power meters are accurate to within +/- 1.0%. This is on par (to slightly better) than the majority of other power meters on the market.

Cadence Detection
Like most power meters, both the 2INpower and INpower use an accelerometer, hidden inside the axle, to measure cadence.

ROTOR power meters come with a full two-year manufacturer’s warranty.
