How to Change a Bike Chain How to Change a Bike Chain

Every bike chain will need to be replaced from time to time. According to bicycle repair experts, a bike chain will last between 2000 and 20,000 miles. It greatly depends on the type of terrain you ride and how well you maintain the parts on your bike.

Change a Bike Chain

If it has rusted out or otherwise been corroded, you’ll need to change your bike chain. To do this, you don’t need a repair stand, although that helps. The tool you will need is called a link removal tool.

First, set the gears on your bike to the highest combination so the chain is wide apart and lay the bike on its left side.

Then, position the link removal tool on the chain so that its internal pin aligns with a pin in one easy-to-reach chain link. Hold the tool in place and turn the crank so that the internal pin pushes on the chain link pin and pushes it out–but not all the way. Once separated, the chain will easily come off.

Once it’s off, thread your replacement chain around the gears making sure it is not twisted. Use the link removal tool to hold the two ends of the new chain together. The tool works in the same way to put a chain together as to separate it. Turn the crank to push the pin into the link, thus fastening the chain.

Finish the whole procedure by lubricating the new chain. It’s a good idea to lubricate the bike chain periodically to extend its life.
