A sensor installed on the crank
set is coming into contact with
the frame, Di2 battery, brake,
or other provided component.
The frame is not supported.
Depending on the shape of
the frame being used, a crank
that has sensors installed may
not be installable because it
comes into contact with the
frame. Even when two frames
have the same model number,
a difference in size and/or
year may make installation
impossible.
When the Di2 battery is under
the chain stay, installation that
provides contact with the Di2
battery may not be possible.
Take your bicycle to your retailer and have its size measured to check whether
the frame is supported. Since actual measurement is required, a judgment
about whether a frame is supported cannot be made before the frame is sold.
The crank set is obstructing
the transmitter and cover.
The crank set is not supported. Contact your dealer. Before selling the product, conrm that
the crank set is supported.
Shimano genuine chainrings are
supported.
I cannot assemble the outer
chainring correctly.
The installation has been done
incorrectly.
Contact your dealer. The gap between the junction box and
the outer chainring is too narrow.
Refer to the documentation for the
crank set when assembling the chain
ring, and install it so the spider arm
does not contact the junction box.
There is a noise when I am
riding. The transmitter and
cover rattle.
The screws for installing the
sensor have become loose.
The double-sided tape or the
parts of the sensors have
deteriorated.
Contact your dealer.
You may need to replace the double-
sided tape or the parts of the sensors
if they deteriorate. (This is a paid
service.)
Check the screws for xing the right
transmitter, and then retighten them.
Check if the parts of the sensors are
installed correctly.
If replacements are needed, please
visit our website.
The chain ring rattles. The crank set is not correctly
assembled. The chain ring
adapter is not correctly
installed. The chain ring bolt
has become loose.
Contact your dealer. Check if the chain ring adapter is
installed correctly. Press on the
chainring in a clockwise direction
to eliminate any play as you tighten
the chainring bolts to the specied
torque. Retorque the chain ring bolt
periodically. Refer to the documentation
for the crank set.
Fix the position of the right transmitter
after assembling the chainring.
When the right transmitter’s
cover and left battery’s cover
were installed, the seal was
weak.
The rubber gasket is
deteriorating.
We recommend periodically replacing
the rubber gaskets inside the right
transmitter and left transmitter’s battery
cover. (This is a paid service.)
Using the equipment while the rubber
gaskets have deteriorated may
damage the product.
Contact your dealer.
Replace the rubber gaskets.
If replacements are needed, please
visit our website.
There is sand or oil on
the rubber gasket in the
transmitter.
― It is necessary to replace the rubber
gaskets if bicycle oil, cleaner, mud, or
sand has gotten on them, even if they
are not deteriorated. (This is a paid
service.)
Contact your dealer.
Replace the rubber gaskets.
If replacements are needed, please
visit our website.
