Installation tips
When changing your derailleur, check the condition of the cabling. If the cable is frayed or oxidized, we recommend changing it.
Check that the derailleur hanger is correctly aligned so that you can make adjustments. Replace or straighten if necessary.
Maintenance tips
Clean your derailleur with slightly warm soapy water.
Avoid degreasing products that damage plastics.
