PART II
Some freestyle bicycles are equipped with a cable
detangler for the rear brake. See diagram of the cable
routing. If the upper cable is not already assembled,
insert the cable barrel end into the right (rear) brake
lever. Adjust the brake lever adjustment barrel so that
the slots line up with the brake lever and insert the upper
cable through the brake barrel slots. Rotate the barrel
so that the slots are no longer in line. Note that on the
upper cable, one of the cable casings is shorter than
the other. The shorter side should be on the right. This
is the shorter distance between the brake lever and the
upper detangler plate. Thread the adjusting barrels in
on both sides, and hook the cable ends into the bearing
unit. Note that the lower cable should already be hooked
into the lower tabs of the bearing unit. (gure above)
Next try squeezing the brake lever several times to be
sure all the cables are seated in the adjustment barrels. If
there is excess play before the brake cable starts to move,
this can be adjusted by unscrewing one or more of the
adjustment barrels.
First adjust the barrel adjuster at the mid point of the
upper cable until the brake lever does not have any free
play. Next squeeze the brake lever and allow it to return.
Check to see if the bearing unit bottoms out on the lower
detangler plate? If so, unscrew the adjust barrel further
until the bearing unit sits about 1mm above the lower
plate. This is the correct position for the bearing unit.
Rotate the handlebars back and forth, and then turn them
completely around 360 degrees. Note whether the bearing
unit spins quietly, or if it “ops” back and forth? If it has
any op, this can be ne tuned with the 4 adjustment
barrels in the upper and lower detangler plates.
The goal is to reduce or eliminate as much of the op
as possible, while keeping the brake function consistent.
While turning the handlebars 360 degrees, note whether
the plate ops forward and back, or if it ops the same
way. If it ops forward and back, adjust the upper cable
barrel adjusters until the op is reduced. If the op is
the same way, then adjust the lower cables until the op
is reduced. Sometimes both need to be adjusted. The
best thing to do is to adjust the lower cables rst until the
bearing unit has an equal gap on the left and right sides,
then adjust the upper barrel adjusters until the op is
minimal or none at all.
Now follow the brake adjustments for the type of brake
the bike is equipped with (Caliper or U brake).
