7. Cables, Housings, And Bar Assembly
This section explains how to install housings in the aerobar, mono-extension, and frame;
and how to assemble the bar. Figure 7.1 shows an exploded view of the bar assembly.
If you are assembling a new bike, don’t be confused by the backwards cables in the housing;
those cables are just there to hold the housing in place during shipping.
If you are replacing cables or housing, you must remove the aerobar before proceeding.
Tools and materials required
• Torque wrench
• 3 and 4 mm hex wrench
