TUNING THE GEARS - REAR DÉRAILLEUR
|
BARREL ADJUSTER
|
To adjust the dérailleur cable tension, shift the
chain onto the smallest sprocket and try to shift
on to the second sprocket by changing the gear on
the handlebar.
|
If it doesn’t quite make it, rotate the barrel
adjuster on the dérailleur
ANTI-CLOCKWISE TO
INCREASE THE CABLE TENSION.
|
If it over-shifts and tries to get onto the third
sprocket, turn the adjuster
CLOCKWISE TO
DECREASE THE CABLE TENSION.
|
When it works between one and two, check the
shifting across the rest of the gears and tweak the
barrel adjuster if necessary.
|
NEW CABLES CAN STRETCH AND LOSE
TENSION AFTER ITS FIRST PERIOD OF USE.
You’ll notice that the gears move slightly out of
adjustment and will begin to hesitate or over-shift.
|
TO FIX THIS;
you will need to remove the slack
from the cable using the barrel adjustment.
|
If there is lots of slack in the cable and cannot be
taken up using the barrel adjuster, you will need to
pull the excess cable through the clamp, like in the
first step.

WARNING: YOUR GEARS ARE NOT TUNED.
Tuning the
gears correctly is very important. Failure to do so will void your
warranty and may cause injury while riding! If your bicycle has
gears and you are unsure how to tune and adjust them, you must
seek an experienced bicycle mechanic
E
V RY IMPORTANT
Make sure the chain is on the smallest chain ring,
and that the gear shifter is in its lowest position
(lowest gear).
STEP
STEP
Loosen the clamp where the cable is gripped to
the dérailleur.
Pull through any cable slack and tighten.
