The H screw allows you to adjust the lower limit (on the side of the smallest
sprocket).
When you loosen the H screw, the chain is positioned more towards the outside
of the smallest sprocket.
These actions are performed by a quarter of a turn at a time. At each
adjustment, you should achieve a perfect alignment between the sprocket, the
chain and the pulley of the rear derailleur.

Adjusting the cable tension
To adjust a correct sprocket change, use the barrel adjuster on the rear derailleur or the handle. This
barrel adjuster allows you to adjust the derailleur cable tension and to correctly position the derailleur
depending on the chosen speed.
Adjusting the chain
Your bicycle is equipped with an external rear derailleur, the chain is automatically tightened.
Changing the chain
New chains are usually sold with too many links, the first step is to reduce it to the correct length. The
safest method is to count the number of links on the old chain in order to adjust the new one. To remove
the old chain, simply undo a rivet.
Once the chain has been removed, the new one must be fitted. To do so, it must be placed around the
chainring and the rear sprocket so that it meshes properly with the other gear elements. To fasten the
chain closed, we recommend using a quick clamp. This stands in for a female link, inserted between to
male links. The quick clamp also allows you to remove the chain more easily for cleaning.
