1st Tip:
The derailleur hanger helps to ensure the chain catches the rear derailleur. It plays a key role in the working order of the gear shifting mechanism.
2nd Tip:
The derailleur hanger is a component that protects your frame. When the derailleur is subject to an impact, the derailleur hanger can break, but not the frame. We then consider it as bike part subject to wear that might need changing
This service includes:
Removing and mounting the derailleur, replacing the derailleur hanger and adjusting the gears.
