9. Make sure the guide tube, a plastic sleeve that reduces cable friction (Figure 7.16), is in
place inside the brake ferrule. Install the front brake cable. This will hold the ferrule in
place during the next step.
11. Adjust the length of the front brake housing as needed.
12. Install the front brake cable through the lever and aerobar housing.

10. Dry-fit the aerobar to the stem.
Place the ferrule in the stem . Make sure the tabs on the ferrule engage the cut-out in
the stem.
Note: With the low near, medium near, and high near stems, the housing comes in from the
side so the ferrule must be oriented sideways (Figure 7.17).
With all far stems, the ferrule aligns with the centerline of the stem (Figure 7.18).
