# How Long Do Bike Chains Last?

Most mechanics agree that you should replace your chain about every 2,000 to 3,000 miles, depending on your riding style. Many Tour De France riders wear out two or even three chains on their primary bike over the course of the three-week race.

• Generally, bike chains last 2,000 to 5,000 miles, but this time can be shortened or lengthened depending on several factors. Some people may find their bike chain lasting years, while others need to replace every 6 months.

## How often should I replace my bike chain?

To avoid this accelerated wear of your cassette and chainrings, a general rule of thumb is to replace your bike’s chain every 2,000 miles. Mind you, this is just a starting point. No two chains will wear at exactly the same rate because no two riders treat their chains the same.

## How do I know if my bike chain needs replacing?

Another ballpark method for checking chain wear is by measuring it with a ruler. Pick a rivet and line it up at the zero mark. Count 24 more rivets and your last rivet should be at the 12″ mark of your ruler. If it is off by more than 1/16″ your chain is stretched to the point of replacement.

## How long does a mountain bike chain last?

A typical mountain bike chain will last 750 miles of single track riding. It’s not easy to gauge exactly how long a chain will last, but there are ways to prolong the life of the chain.

## How do bike chains wear out?

Basics of chain wear explained Over time, the chain’s pins and inner links will wear, and as a result, the pitch (length) of each link will grow. Because the chain’s overall length grows with wear, chain wear is commonly called ‘chain stretch’ – even though the metal does not (measurably) stretch.

## How do I know if my chain is too long?

Do a simple check on your bike by shifting the chain to the big chainring and the biggest cassette cog; then, push on the end of the derailleur cage (pushing forward) to see how much it will move forward. If it moves just a little, then you’re good. If it moves a lot, then you’ve got too much chain.

## Can I use WD40 on my bike chain?

Can I use WD-40 to lube my bicycle chain? No. You should never use WD40 as chain lubricant since WD-40 is NOT a true lubricant since it’s primary use is as a solvent or rust dissolver.

## How much does it cost to replace a chain on a bike?

How much does a bike chain cost to replace? Entry level chains can start off around \$15.00 with more expensive and higher performance chains ranging from \$25.00 to \$60.00 or more. More expensive chains increase shift quality and are generally more durable as they wear.

## How much should a bike chain cost?

A bike chain costs anywhere from \$10 to \$90 depending on the brand, quality, and type of bike you’re buying it for. Basic, cheaper bikes that need a simple chain will be closer to \$10. Higher quality chains that are durable and made for top notch road bikes will cost \$60 to \$90.

## How long should a cassette last?

Cassette lifespan can range between 4000 to 10000 miles, and this is affected by the cassette itself and maintenance frequency.

## How long do Shimano chains last?

A chain can last anywhere from about 500 miles to 5000, depending on the quality of the chain, the sprockets, how the bike is ridden, and the maintenance.

## How can I make my bike chain last longer?

Proper bicycle chain lubrication not only makes shifting gears easier but also ensures the drivetrain lasts longer. If you experience shifting issues, you might be overdue for a new chain. Replacing the chain at regular intervals will make the cassette, the cluster of sprockets on your bike’s rear hub, last longer.

## How long should a chain be?

After a measurement is obtained, its a good idea to opt for a necklace size that is at least the second size up from your neck size. For example, if you have an 18 inch neck, you should probably choose a chain length of 20 inches or more. An 18 inch chain would feel too tight.

## Are bicycle chains universal?

All modern bicycle chains are made to the “one-half inch pitch” standard, meaning from rivet to rivet is nominally 0.5 inches. However, this does not mean all makes and models of chains are interchangeable. There are two basic types of bicycle chains: “one-speed” chains, and derailleur chains.
