Frequently Asked Questions
Everything you need to know about the world's leading bicycle chains.
How do I know which chain is compatible with my drivetrain?
Compatibility is primarily determined by the number of rear cassettes on your bike. We offer specific chains for 9, 10, 11, and 12-speed systems. Please check your derailleur specifications or existing chain markings before purchasing.
What is the average lifespan of a KMC chain?
While lifespan depends on riding conditions and maintenance, our premium chains typically last between 3,000 to 5,000 kilometers. Using a chain checker tool regularly will help you replace it before it causes wear on your chainrings and cassette.
Do KMC chains come with a MissingLink connector?
Yes, almost all KMC chains include our patented MissingLink connector in the package, allowing for easy, tool-free installation and removal for cleaning.
What is your return policy for incorrectly ordered sizes?
We accept returns within 30 days of purchase, provided the chain is in its original, unopened packaging and has not been cut or installed on a bicycle.
How long does shipping take for domestic orders?
Standard shipping typically takes 3-5 business days. We also offer expedited shipping options at checkout if you need to get back on the road or trail sooner.
Are KMC chains compatible with Shimano, SRAM, and Campagnolo systems?
Yes, KMC chains are designed to be 'non-directional' and are 100% compatible with all major drivetrain brands, often providing smoother shifting and higher durability than OEM parts.
