IMPORTANT: The brake lever body unit must be firmly attached to the handlebar. Otherwi
-
se, it may move on its own while riding. Note, however, that the brake lever body unit can
still rotate away in the event of a strong impact in order to protect the brake in the event
of a fall.
CAUTION: Risk of falling, accident, injury and death if the brake lever body unit is twisted while
riding.
Step 5: Adjusting the Root-Lever Pro
Due to the combination of EPA and CPA system, the brake lever can be adjusted to al-
most any rider preference, which allows versatile brake adjustment possibilities. For your
own safety, however, we recommend that you have the brake lever adjusted by a qualified
technician at a bicycle workshop in accordance with these instructions. It is essential to
ensure that the brake is fully functional.
IMPORTANT: If there is air in the brake system, if the Root-Lever Pro is incorrectly adjusted
or if the brake is continuously applied during long descents, the brake system may block
unexpectedly, as the hole to the compensation reservoir may become permanently closed.
Installing the CPA screw (Fig. 1).

First, the bite point of the brake / Root-Lever Pro must be set. The braking force begins
at the bite point of the Root-Lever Pro. To do this, screw in the CPA screw so far that the
bite point is positioned according to your preferences, but at most so far that the screw is
in contact with the encoder piston when the brake lever is not tightened (Fig. 1). The CPA
screw should therefore only be screwed in so far that the encoder piston is not activated.
When adjusting the CPA screw, always ensure that it does not activate the brake lever
body unit piston even when the end stop is reached (marked in Fig. 3).
