How to Choose a 12 Speed Chain
12 speed drivetrains use the narrowest chains, so getting the right one matters. The most important question is whether your bike uses a standard 12 speed chain or a SRAM flattop chain.
Standard or Flattop?
Shimano 12 speed and most other 12 speed systems use a standard 12 speed chain such as the KMC X12, SunRace 12 Speed or VG Sports 12 Speed. SRAM AXS flattop, Transmission and T-Type drivetrains need a flattop chain, such as the KMC XSL FlatW. A standard chain will not work correctly on a flattop system, and a flattop chain will not suit other systems.
Pre-Waxed Chains
The KMC X12 Pre-Waxed, X12LW and XSL FlatW arrive treated with KMC GO wax. Waxed chains run with low friction, stay cleaner and pick up less grit than oiled chains, which means less wear on your cassette and chainrings. The X12LW and XSL FlatW Aurora Blue and Gold come in a limited edition box, making them a great gift.
Finishes and Coatings
The KMC X12 comes in Black, Titanium Nitride Gold and the multi-coloured Aurora finish. Titanium Nitride is a hard coating that helps the chain resist wear and corrosion, not just a colour.
12 Speed e-Bikes
If you have a 12 speed e-bike, the KMC e12 is built to handle motor torque with over 1,000kgf of tensile strength. See all our e-bike chains.
When to Replace Your Chain
A worn chain quickly wears out an expensive 12 speed cassette. Check your chain regularly with a chain checker and replace it at or just before 0.5% wear.
12 Speed Chain FAQs
Will a Shimano 12 speed chain fit SRAM?
Standard 12 speed chains suit SRAM 12 speed Eagle and road systems that use a standard chain. SRAM flattop and T-Type drivetrains need a flattop chain.
What is a flattop chain?
A chain with flat-topped outer plates, made for SRAM AXS flattop, Transmission and T-Type drivetrains. The KMC XSL FlatW is a flattop chain.
Should I oil a pre-waxed chain?
No. Adding oil defeats the purpose of the wax. Top it up with KMC GO chain wax instead.
How many links does a 12 speed chain need?
Most 12 speed chains come with 126 links, which suits bikes with large cassettes. Shorten it to fit your bike with a chain tool.
Do I need a special connecting link?
Yes, use a 12 speed connecting link. Many of our 12 speed chains include a MissingLink.
