9. FREQUENTLY ASKED QUESTIONS
9.1. GENERAL
ROTOR INpower vs 2INpower?
ROTOR INpower measures in the spindle power
generated by the left leg. The power value that's
shown is the result of extrapolation (default operation
to multiply by two) power measured in the left leg.
ROTOR 2INpower keeps INpower technology and
adds strain gauges to the drive-side crank, which
allows the measurement of the power applied by each
leg independently. In addition to the new metrics that
ROTOR INpower introduced for pedal analysis and
monitoring: TORQUE 360 and OCA (Optimum
Chainring Angle), ROTOR 2INpower goes further
allowing analysis for each leg separately and
providing balance information.

Which Bluetooth devices is ROTOR 2INpower
compatible with?
TM
Any Bluetooth Smart device is compatible with
ROTOR 2INpower, from mobile phones to computers,
with the complete range of Bluetooth Smart cycle
devices in between.
What am I going to find in the 2INpower product
box?
When buying a 2INpower, you will find, in addition to
the crankset, one bolt, one USB cable for battery
charging, an installation and a User Software manual,
and a TrainingPeaks postcard. Training Peaks has
offered 2INpower customers a free premium
account subscription for one month. Visit the site
trainingpeaks.com/ROTOR to obtain the maximum
benefit from this alliance.
How do I know if my frame is compatible with the
2INpower axle?
2INpower is equipped with the UBB30 axle system,
which was introduced by ROTOR. UBB30 axle is a
30 mm axle compatible with almost all standard
frames in the market (when used with the correct
spacers).
ROTOR 2INpower can be installed on your bicycle
even if your current cranks are 24 mm diameter.
UBB30 is compatible with the following road
standards: BB30, PF30, BSA threaded, BBright and
BBright Direct Fit, BB86 and BB386 EVO.
The only frames not compatible with the UBB30
system are the BB90 frames (for 24 mm axle). This
standard uses bearings that are directly pressed into
the frame, without using any intermediate bottom
bracket.
How does ambient temperature affect power
measurements?
Ambient temperature does not positively or negatively
TM
affect how 2INpower works. 2INpower gives accurate
and stable power measurement independently of
changes in temperature during a ride (e.g. long climbs
with higher temperatures at the bottom and lower
temperatures at the top).
It is not necessary to calibrate 2INpower to
compensate for temperature changes.
