Outer casing length
1. Loosen the B-tension adjustment screw until it is in the position shown in the illustration.

2. Check that there is enough slack in the outer casing.
Next align in the outer casing with the bottom edge of the outer casing holder at the rear derailleur and then cut of any excess length of outer casing.

Note:
The distance between the outer stopper to the outer casing holder of the rear derailleur may change when the rear suspension moves, so determine the length of the outer casing at the point where this length is at its greatest.
