If you have purchased the left-crank assembly
with the axle because you already have ROTOR
cranks, you need to substitute the old bolt and
self-extractor nut with the new washer, bolt
and self-extractor nut included in the INpower
package.
Read the user manual carefully to correctly install
these INpower parts. If you have purchased the
complete set of left and right-crank assemblies,
the self-extractor mechanism is already installed
and you do not need to make any modifications.
Do not uninstall the self-extractor set once it has
been successfully installed.
How do I know if my frame is compatible with the
INpower axle?
INpower is equipped with the UBB30 axle system,
which was introduced by ROTOR.
UBB30 is a 30 mm diameter axle which is
compatible with almost all standard frames in the
market (when used with the correct spacers).
ROTOR INpower can be installed on your bicycle
even if your current cranks are 24 mm diameter.
UBB30 is compatible with the following
standards: BB30 (68/73mm), PF30 (68/73mm),
BSA threaded, ITA threaded, BBright and BBright
Direct Fit, BB86, BB386 EVO, BB89 and BB92.
The only frames not compatible with the UBB30
system are BB90 and BB95 (both for 24 mm
diameter axle). These two standards use bearings
that are directly pressed into the frame, without
using any intermediate bottom bracket.
How does ambient temperature affect
powermeasurement?
Ambient temperature does not positively or
negatively affect how ROTOR INpower works.
INpower gives accurate and stable power
measurement no matter changes in temperature
during a ride (e.g. long climbs with higher
temperatures at the beginning and lower
temperatures at the end).
It is not necessary to calibrate INpower due to
temperature changes.
¿Can I disassemble the elements of my power
meter?
No. Inadequate handling of the product will
invalidate the warranty.
The only parts that can be disassembled
are those that are involved in installing and
uninstalling both the cranks on the bicycle,
and the battery and battery cap. Read the user
manual carefully before handling the product.
Never try to disassemble the plastic part at the
end of the left crank and/or the electronics inside
the axle.
Do not try to disassemble the mechanical
elements assembled by the manufacturer, such
as the axle with the left crank, the self-extractor
system, or the spider with the chainrings on the
right side.
How often should the battery be replaced?
ROTOR INpower uses a standard AA 1.5 V
battery. The battery is not included in the original
packaging.
Battery life is usually 300 hours for fully-charged,
alkaline batteries from leading brands. When
the battery is near the end of its life, the ROTOR
INpower cranks will send a message to your
ANT+™ device that will warn you that you'll need
to change it soon.
You can see the battery status by connecting
the crank to the ROTOR User Software running
on your computer. The User Software can be
