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 bike?
Compatibility depends on the number of rear cassettes on your bike. We offer specific chains for 9, 10, 11, and 12-speed systems. Check your derailleur specifications or existing chain markings before purchasing.
What is the expected lifespan of a KMC chain?
Under normal conditions and with proper maintenance, our high-performance chains typically last between 3,000 to 5,000 kilometers. Factors like terrain, weather, and lubrication frequency will affect overall durability.
Do you offer international shipping?
Yes, we ship our products worldwide. Shipping costs and delivery times vary by destination and are calculated at checkout. Please note that international orders may be subject to local customs duties.
What is your return policy for unused products?
We accept returns on all unopened and unused products within 30 days of purchase. Items must be in their original packaging to qualify for a full refund.
Are KMC MissingLinks reusable?
We offer both 'reusable' and 'non-reusable' MissingLinks. Please check the specific product packaging; for safety reasons, we recommend replacing non-reusable links every time the chain is removed.
How should I clean and lubricate my KMC chain?
We recommend cleaning your chain with a soft brush and a bicycle-specific degreaser. Avoid harsh chemicals or high-pressure washers. Always apply a high-quality chain lubricant after cleaning to ensure smooth shifting and prevent rust.
