Installation
Installation to the handlebars
Wind the bracket cover from the front, and then use
a 5 mm Allen key to tighten the mounting nut in
order to secure the bracket cover.
When installing the components to carbon
frame/handle bar surfaces, verify with the
manufacturer of the carbon frame/parts for their
recommendation on tightening torque in order to
prevent over tightening that can cause damage to
the carbon material and/or under tightening that can
cause lack of fixing strength for the components.

some slack even when the handlebars are turned as far as
they will go to the left and to the right.
1.
Gently pull the brake lever.

Pass the inner cable through from
directly in front, set the inner
cable end into the cable hook,
and then install the outer casing
from the opposite side.
The lever stroke can be smoothly
adjusted using the bolt on the top
of the bracket unit. Check the
lever operation while adjusting.
