ROTOR INpower V3 Road Power Meter

ROTOR INpower V3 Road Power Meter

The all-new ROTOR INpower V3 Road Power Meter now features an updated gloss black aluminum finish. As with the previous generation INpower, the INpower V3 gets 300-hours of battery life is accurate to +/- 1.5%. This high level of accuracy is accomplished by using two sets of opposing strain gauges in the axle. The strain gauges can measure power, cadence, torque effectiveness and pedal smoothness. In addition, because all of the electronics are housed inside the waterproof, sealed axle, the power meter is super durable and can withstand the harshest conditions.

In addition, the new ROTOR INpower V3 uses ROTOR’s Direct Mount Chainrings. The Direct Mount rings are machined from a solid block of 7075 aluminum which makes them lighter and stronger than the standard 2x chainring set-up. The power meter has ANT+ and Bluetooth SMART, is powered by a AA battery and is compatible with all bike computers and training apps.

Advice From Our Staff:

The advantages to this power meter are it’s relatively affordable (as far as ROTOR power meters go), the aluminum crank arms are light and stiff, the ROTOR direct mount chainrings further increase stiffness and this power meter makes it easy to run oval rings. The drawback is that it only measures left leg power, whereas most power meter cranksets measure power from both legs.
