METRICS
How often are the power values shown?
ROTOR INpower becomes active after pedaling
starts.
Sampling frequency is 200 Hz, which means that
force data are measured 200 times per second.
The data sent to the ANT+ device are from the
last completed pedal rotation. How long a single
pedal rotation lasts depends on the cadence of the
cyclist, for example, if the cyclist pedals at 90 rpm
then the rotation lasts 0.67 seconds.
The power measurement of a rotation is sent
according to ANT+™ protocol: 4 times per second.
How data are recorded and accumulated depends
on the ANT+™ device. Devices usually offer the
option to record data once per second, or to
record data in "Smart" mode.
Which data related to power are provided by
INpower?
INpower processes and provides values of:
Power, Cadence, Torque Effectiveness and Pedal
Smoothness.
A balance value is also shown, which is set by
default as 50%/50% (assuming a perfectly-
balanced cyclist).
INpower also calculates and shows additional
information that can only be viewed through the
User Software: TORQUE 360 and OCA (Optimum
Chainring Angle).
How can I see Torque Effectiveness and Pedal
Smoothness data?
Both metrics are accessible by ANT+-compatible
device manufacturers and it is their decision
whether to show them or not on their devices.
Most ANT+-compatible devices already feature

these metrics' recordings and visualizations.
How can I see the TORQUE 360 graph and my
OCA value?
Currently these data are only accessible using the
User Software that can be downloaded for free
from ROTOR's website. Once you have successfully
downloaded and installed the software, you will
need a USB ANT+ stick to receive data sent by
INpower (stick not included, contact your ROTOR
retailer or local distributor to obtain one).

more about TORQUE 360 and OCA.
What is 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.
What is OCA?
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.
