To calculate the OCA, I
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®.
P
ositions are marked by OCP (Optimum
Chainring
Position) points on the chainrings
and right crank
.
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.

Is it necessary to install a cadence sensor on my
bicycle?
Your ROTOR INpower cranks have a cadence
®
sensor incorporated in the axle and do not need
an external sensor.
It is recommended to uninstall any cadence
sensor from your bicycle to avoid interferences.
