In case your derailleur takes a success throughout your experience, the derailleur hanger is there to soak up the influence. If the hanger will get broken or bent, you may want to exchange it.
Instruments you’ll want:
Eradicating the Derailleur Hanger
Begin by taking the rear wheel off your bike.
Subsequent, use the hex wrench to loosen and take away the bolt that connects the derailleur to the hanger. It is wonderful to let the derailleur dangle from the shift cable whilst you work.
Now take away the hanger insert from the dropouts on the body with a hex wrench. Some hangers may have two halves to take away.
Putting in the Derailleur Hanger
Earlier than putting in the alternative hanger, clear off the dropout space with bike cleaner and a rag. Then lubricate each the within and out of doors of the body with bike grease.
Now you’ll be able to set up the brand new hanger and tighten it into place utilizing a hex wrench.
Grease up the threads on the derailleur mounting bolt and reconnect the derailleur. Use a torque wrench to tighten the bolt to the producer’s specified torque.
Now reinstall the rear wheel and ensure the gears are shifting usually.
