Thread A Chain On To A Bike’s Rear Derailleur
Introduction
If the chain looks and sounds right then it's usually following the correct path on the rear derailleur. If you're uncertain about this, look carefully at the old chain's route before you take it off, take pictures or make a sketch.
Step 1
Off The Ground
Hang the bike up or put it in a stand so the back wheel can turn.
Step 2
Set The Gear on the front and rear derailleur
If the rear derailleur has a cable connected select the highest gear. If the front derailleur has a cable connected select the lowest gear.
Step 3
Use The Small End
If one end of the chain has a pin sticking out, thread the other end through the system.
Step 4
Insert The ‘C’ Hook
Hang the ‘C’ hook near the end of the chain so it can’t pass through the rear derailleur.
Pro Tip
Don’t let the chain drag on the floor. It will pick up dirt.
Step 5
Start At The Back
Run the chain up behind the bottom jockey wheel of the rear derailleur.
Step 7
Top Jockey Wheel
Pass the chain up around the front of the top jockey wheel on the rear derailleur.
Step 10
Front Derailleur
Pass the chain through the front derailleur cage and engage it on the small cog at the front.
Step 12
Hook Up
Connect the chain coming down the front of the small cog at the front to the ‘C’ hook in the other end of the chain. The chain is now ready to be connected.
