Bike Chains | 6 to 12 Speed Chains Shimano, SRAM & KMC

What is a bike chain?

A bike chain is a key component of the drivetrain that transfers power from the pedals to the rear wheel.

When you pedal, the chain moves over the chainrings at the front and the cassette or freewheel at the rear, driving the bike forward.

Bike chains are made up of interconnected parts. This includes inner plates, outer plates, rollers and pins.

These components work together to create a flexible but durable system that can handle constant movement and load.

Types of Bike Chains

Different bikes need different types of chains depending on their drivetrain.

Single-speed chains. Used on bikes with one gear, such as BMX, fixies and many kids bikes. These are wider and more robust.
Multi-speed chains. Designed for geared bikes, including road, mountain and hybrid bikes. These chains are narrower to allow smooth shifting across many gears.
E-bike chains. Built to handle higher torque from electric motors, offering increased strength and durability.

How to Choose the Right Bike Chain

Choosing the correct chain is essential for smooth shifting and drivetrain longevity.

Match Your Speed

Chains must match the number of gears on your bike cassette:

Single-speed. Typically also called 1/8" chains. Browse our single speed bike chain collection.
6/7/8-speed bike chains. Wider multi-speed chains (often interchangeable).
9-speed. Common on mid-range MTB, hybrids and entry-level road bikes. Browse the 9-speed bike chains range.
10-speed bike chains. Found on mid-range road and upper mid-range MTB bikes.
11-speed bike chains are widely used across road and MTB drivetrains. Explore our 11 speed bike chain range.
12-speed chains are designed for high-performance. Browse out 12 speed bike chain collection.

Tip: Always match your chain to the number of cogs on your cassette.

Also ensure the speed of your rear derailleur matches your chain.

Check Brand Compatibility

Performance is best when matched with your drivetrain brand.

Match your cassette brand to your chain. So, if you have a Shimano cassette, use a Shimano chain.

But there are exceptions:

Brands like YBN and KMC, deliver exceptional performance due to unique coatings and chain profiles.

And they make their bike chains compatible with the other major players.

How to Maintain Your Bike Chain

Proper chain care results in better performance and longer bike life.

Basic Maintenance Tips

Clean your chain regularly: Every 100–200km for MTB, 300–500km for road bikes.
Lubricate after cleaning: Use a dry lube for dry conditions, wet lube for wet/muddy rides.
Check chain wear: A worn chain can damage your cassette. Use a chain checker tool or visit one of our stores for a quick check.

Avoid These Common Mistakes:

Don’t over lube (it attracts dirt).
Don’t use household degreasers that damage your drivetrain.

Bike Chain FAQs

What size bike chain do I need?

You need a chain that matches the number of speeds on your cassette (e.g. 9, 10, 11 or 12 speed).

Chains are not interchangeable across all speeds.

Are all chains compatible?

Not always.

While some chains work across brands (like KMC and YBN), it’s best to match your chain to your drivetrain (Shimano, SRAM, etc.) for optimal performance.

How often should I replace my bike chain?

Most chains should be replaced every 3,000–5,000 km depending on riding conditions.

Regular checks with a chain wear tool are recommended.

What happens if I don’t replace a worn chain?

A worn chain can prematurely wear your cassette and chainrings, leading to more expensive repairs.

Do e-bikes need special chains?

Yes.

E-bike chains are reinforced to handle higher torque and typically last longer under load.
