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.

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. Figure A5 IA // ROUTING MANUAL...
(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...
