V. Adjusting the gear changing system
Your bike has several manually interchangeable gears thanks to a
Shimano lever system with a rear derailleur and possibly a front
derailleur. Use the right-hand lever to change the rear sprocket and
the left handle to change the front chainring. On a hill, the small
chainring and the large pinion facilitate pedalling. Adjust your gear
ratio (chainring/pinion) as needed.
Careful, never pedal backwards during the gear change and never
force the control lever.
For optimal use of the gear change system, it is recommended that
you do not change gear when you are pedalling hard.
1. Adjusting the limit screws
The derailleur's range of movement can be adjusted with the H and L screws.
The L screw can be used to adjust the upper limit (on the side of the large
sprocket).
When you loosen the L screw, the chain is positioned more towards the
outside of the large sprocket.
The H screw can be used to adjust the lower limit (on the side of the small
sprocket).
When you loosen the H screw, the chain is positioned more towards the
outside of the small sprocket.
These actions are carried out by a quarter turn. With each adjustment, you
should obtain a perfect alignment between the sprocket, the chain and the
pulley of the rear derailleur.

2. Cable tension adjustment
To adjust a sprocket change correctly, use the wheel on the rear derailleur or the lever. This wheel
allows you to adjust the tension of the derailleur cable and to position the derailleur correctly
according to the speed selected.
