TORQUE 360: INpower's technology allows us to feature — among other data, the
polar curve of the effective torque — or force — applied to the pedal, which intuitively
visualizes the distribution of power exerted at different angles throughout a pedal rotation.
The fact that the ROTOR INpower axle doesn't measure the combined power of both legs
same as other systems in the market, but rather measures the left leg independently,
allows us to analyze the complete pedal rotation and how power is delivered both in the
descending phase of a pedal rotation (positive) and the ascending phase of a pedal rotation
(usually a negative reference).
The polar display is useful to know your pedaling pattern in order to improve your
technique.
OCA: stands for Optimum Chainring Angle and is one of the new data features
offered by ROTOR INpower.
OCA determines the angle in degrees, measured from the dead spot at the highest point, in
which the effort's barycenter (area enclosed by the torque curve or the force curve) is shown
in the Torque 360 graph.
To calculate the OCA, INpower takes into account all torque values, both positive and
negative (the pedal stroke's rebound).
The OCA is closely linked to ROTOR Q-Rings, since the OCA (Optimum Chainring Angle)
suggests in which position to install your Q-Rings, positions are marked by OCP (Optimum
Chainring Position) points on the chainrings.
A range of OCA values corresponds to OCP points. For example, if your OCA is between
87º and 93º, you should start using Q-Rings in OCP #3.
