Installing a bicycle chain is a straightforward process that can be done with a few tools. Here are the steps to install a bicycle chain:
-
Measure the old chain: Use a chain tool or a ruler to measure the length of the old chain to determine the length of the new chain needed.
-
Remove the old chain: Shift the chain into the smallest chainring and smallest cog, which will allow the chain to be easily removed. Then use a chain tool to push the pin out of one link of the chain, separating it into two pieces.
-
Prepare the new chain: If the new chain comes with a master link, skip to step 5. If not, use a chain tool to press a link pin out of one end of the chain.
-
Join the two ends of the chain: Place the two ends of the chain together, making sure the teeth of the inner plates mesh correctly. Then use a chain tool to press the pin back into the link, joining the two ends of the chain.
-
Install the chain: Shift the chain onto the smallest chainring and smallest cog. Then route the chain through the derailleur and around the largest chainring and largest cog.
-
Connect the chain: If the chain was prepared with a master link, simply snap the master link together. If not, use a chain tool to press a link pin into the chain to join the two ends.
-
Check the chain tension: Shift through the gears and apply some pedal pressure to make sure the chain is properly tensioned and there is no slack.
It's always a good idea to lubricate the chain after installing it to help extend its lifespan and improve shifting performance.
