INTRODUCTION
Congratulations on acquiring a Felt IA triathlon bike, and thank you for being a member of the
“Felt family.” This guide is intended to provide instructional support for mechanics wishing to route
mechanical wires, electronic wires, and brake hoses in their IA frame modules. Please note that the
procedures depicted in this guide require above-average ability in bicycle mechanics, as well as
special tools. If you are not a highly-skilled or experienced bicycle mechanic, we strongly
recommend you take your bicycle to an authorized Felt Bicycles retailer in order to obtain the
highest quality results.

IA with Shimano Di2 Electronic Drivetrain (with RS910 junction)
PARTS
(2) Brake hoses
(7) Shimano E-tube wires
(1) Shimano “Y” E-tube connector (Shimano part number EW-JC130)
(2) Shimano Junction B
(1) Shimano Junction A (Shimano part number RS910)
(1) Felt 8mm port, 2.5mm hole, conical grommet (“8mm/2.5mm conical grommet”)
(1) Felt 8mm port, 2.5mm hole, flat grommet (“8mm/2.5mm flat grommet”)
NOTE
In the following diagrams, blue, purple, and green components are electronic wires; and red compo-
nents are brake hoses.
SHIFTERS
STEP 1
Start at the basebar. See Figure A1. Using a Shimano “Y” E-tube connector (Shimano part number
EW-JC130), connect its two electronic shift wires located where the brake levers will go, and connect to
the Junction B box located under the front cover. Connect an electronic wire (850mm) to each shifter
located in the aerobar extensions, and then connect them to the Junction B box located under the front
cover.
Figure A1

STEP 2
From the Junction B box located under the front cover, connect a (1200mm) wire to it and route
through the stem and into the frame where the top tube-mounted storage box is located.
Then continue routing through the downtube to Junction B box located around the bottom bracket
area. See Figure A2.

IA // ROUTING MANUAL 5
STEP 3
- See Figure A3.
- Connect an electronic wire (300mm) from the Junction B box located near the bottom bracket to the
Junction A (RS910) located underneath the bottom bracket shell.
- Connect an electronic wire (300mm) (shown in green in Figure A3) from Junction A (RS910) to the
battery.
- Connect a wire (300mm) from the Junction B box located near the bottom bracket to the front derail-
leur using the 8mm/2.5mm flat grommet.
- Connect another wire (750mm) from the Junction B box to the rear derailleur and install using the
8mm/2.5mm conical grommet.

REAR BRAKE HOSE
NOTE
A Park Tool IR-2 specialty tool is very helpful when doing some of the next steps, but is not necessary.
STEP 1
Using the correct length of hose (see Appendix A, “Wire & Hose Lengths”), start from the rear brake
caliper. Have the brake hose enter the non-drive-side chainstay and route over the bottom bracket
shell. Then feed the hose up through the downtube. See Figure A4.
Figure A4
STEP 2
Exit where the integrated storage compartment is positioned along the top tube. Route through the
stem and then into the basebar, then towards the brake lever. Here you’ll be able to connect the brake
hose to the brake lever. See Figure A5.

IA // ROUTING MANUAL 7
FRONT BRAKE HOSE
STEP 1
Make sure that your frame’s front headtube cover is removed for easier access and visibility. Using the
correct length of hose (see Appendix A, “Wire & Hose Lengths”), start by routing the front brake hose
into the fork and feed the hose upwards. The hose should exit behind the front headtube cover. See
Figure A6.
Figure A6

IA // ROUTING MANUAL 8
STEP 2
Feed the hose into the stem, then out and into the basebar. Route the hose to the brake lever. Here
you’ll be able to connect the brake hose to the brake lever. See Figure A7.

IA // ROUTING MANUAL 9
USING A DIRECT-MOUNT BAR/STEM
If you are using an integrated basebar, please note the following diagram in regards to routing ca-
bles and hoses in and around the bar (all other steps are the same). See Figure A8. Using a Shimano
“Y” E-tube connector (Shimano part number EW-JC130), connect its two electronic shift wires located
where the brake levers will go, and connect to the Junction B box located under the front cover. Con-
nect an electronic wire to each shifter located in the aerobar extensions, and then connect them to the
Junction B box located under the front cover.

EW-JC130), connect its two electronic shift wires located where the brake levers will go, and connect to
the 4-port Junction A box located under the front cover. Connect an electronic wire (850mm) to each
shifter located in the aerobar extensions, and then connect them to the Junction A box located under
the front cover.

Connect a wire (1200mm)—shown in purple in the diagram—to the Junction A box located under the
front cover and route through the stem and into the frame where the top tube-mounted storage box
is located. Then continue routing through the downtube to Junction B box located around the bottom
bracket area. See Figure B2.
