9.3. POWER INFORMATION.
METRICS
How often are the power values shown?
ROTOR become active after pedaling power meters
starts.
Sampling frequency is 200 Hz, which means that
force data are measured 200 times per second.
The data sent to the
device are from the computer
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 computer device.
Which data related to power are provided by
INspider?
INspider processes and provides values of: Power,
Cadence, estimated Left-Right Balance
TORQUE 360 and OCA (Optimum Chainring Angle).
These are ROTOR INpower technology speci
fi
c.
Additional information that at the moment can only
be viewed through the
or the ROTOR
User Software
Power app is calculated and shown too. These are
Manual_ _ES_EN 2INpower
Some cycle computers like the Sigma ROX12.0
and the Xplova X5 EVO now include special
compatibility with ROTOR power meters, being
able to provide real time OCA and OCP values
and to save them for further analysis too.
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
displays different the distribution of power exerted at
angles through a pedal rotation.
The fact that the ROTOR INpower
doesn
’
t ® technology
measure the combined power of both legs same the
as other systems in the market, but rather measures
each
the leg independently, allows us to analyze
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 to help you improve your pedaling technique.
What is OCA?
OCA stands for Optimum Chainring Angle and is
one of the new data features offered by ROTOR
I power
. N ® technology
OCA determines the angle in degrees, measured
from the dead spot at the highest point, in which
the effort
’
s barycenter ( area enclosed by where the
the is divided by two torque curve or the force curve )
is shown in the graph. TORQUE 360
To calculate the OCA, I ® technology Npower takes
into account all torque values, both positive and
negative (the pedal stroke
’
s rebound).
The OCA i ® s 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. ®
