Frequently Asked Questions
Everything you need to know about KMC high-performance chains and service.
How do I know which chain is compatible with my drivetrain?
KMC chains are designed to be compatible with all major drivetrain systems including Shimano, SRAM, and Campagnolo. Simply match the speed of your cassette (e.g., 10-speed, 11-speed, or 12-speed) with the corresponding KMC chain model.
What is the expected lifespan of a KMC chain?
While lifespan varies based on riding conditions and maintenance, our high-durability series typically lasts between 3,000 to 5,000 kilometers. Regularly cleaning and lubricating your chain will significantly extend its performance life.
Does my chain come with a MissingLink connector?
Yes, every KMC chain includes a patented MissingLink connector in the package. This allows for easy, tool-free installation and removal for maintenance.
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 your components ready for an upcoming race or weekend ride.
What is your return policy for unused products?
We offer a 30-day return policy for all items in their original, unopened packaging. If the chain has been cut or installed on a bicycle, it is no longer eligible for a return due to safety and quality standards.
Are KMC chains covered by a warranty?
Yes, we offer a satisfaction guarantee and a limited warranty against manufacturing defects. If you experience premature wear or a structural failure under normal use conditions, please contact our support team for an inspection.
