Why is an old chain unsafe?

Asked by: Craig Keita

A worn, stretched chain will accelerate wear on sprocket and chainring teeth. There will then be a greater chance that the chain will slip off of and override the sprocket teeth as you apply a power stroke through the crank.

What happens if you wear a chain too long?

Why? A chain that’s too long (loose) may cause dropped chains and/or inconsistent shifting — front and back shifting. A chain that’s too short (tight) can cause even bigger problems.

What happens if you ride with a worn chain?

Prevent wear



The problem is that when you ride a bike with a worn out chain you start doing damage to other drivetrain parts, namely your cassette and even your chainrings. The stretched chain wears out and can damage the teeth on the cassette. At this stage it is pointless to just replace the chain.

Does a rusty chain matter?

Rust on your chain is no good–it creates additional friction, places wear on your other drivetrain components, and makes the chain more susceptible to breakage.

between 1,500 and 3,000 miles

Expect between 1,500 and 3,000 miles from a 10-speed chain. It helps to establish what counts as ‘worn out’. A chain is worn enough to affect transmission efficiency when it lengthens by 0.75% but has some life left if extended mileage is the aim, in which case it should ideally be replaced when it lengthens by 1%.

How do you know if your chain is too long?
