13. Install the mono-extension assembly (mono-extension, pivot cradle, and mono-spacer)
on the aerobar.
With the aerobar in place on the stem, pass the front attachment bolt up through the
stem, the bar, then into the mono-extension assembly (Figure 7.19). Tighten until finger
tight.
14. Connect the cables (Figure 7.20) and assemble the aerobar and stem.
Place the ferrule in the stem again. With a double ferrule, connect the rear brake housing
from the aerobar to the frame housing while you slide the rear brake cable through.
15. Connect the shift housing from the mono-extension to the shift housing from the frame.
The rear brake housing should be in the middle (Figure 7.20).
Insert the shift housings into the double ferrules. Make sure to connect front to front.
To allow space to close the stem cover, push the double ferrules as far as possible
forward or back in the stem, and make sure they are not in contact with the steering axle
or steering axle pinch band.

16. Loosen the front bolt five to six turns to allow the back of the mono-extension assembly
to tilt. This tilt provides clearance for the stem cover to drop into the rear cutout of the
aerobar (Figure 7.21).
