Why must I change my chain? It doesn’t look like it’s worn off and it still is working fine!
Oh yes, that statement is true but you are plainly judging from your naked eye. If you fail to change the chain when it is due, you are shortening the lifespan of your cassette and gear on the crank. Then, you might even need to change your drivetrain!
Penny wise, Pound foolish then.
So how do we measure age of the chain? All you need is a ruler.
- If the distance between one pin to another pin is an exact measurement of ½ inch. It means your chain is in good condition and you don’t have to change the chain.
- If the distance between one pin to another is reaching 1 inch, you should consider replacing the chain.
- If the distance between one pin to another has passed 1 inch, you MUST change the chain! Check also your sprocket, crank and Rear Derailleur pulleys. These components might also be worn off.
Basically the total lifespan of a chain wear is approximately 2,000km to 2,500km; whereas the good condition is very much dependent on the maintenance of the chain.
