Mountain bike chains endure significant abuse as not only do they spend extensive time in mud and grime, they still have to function seamlessly within the bike's transmission, maintaining high strength for challenging climbs.
Regular degreasing and lubrication can help minimise chain wear, but when the time comes to replace a mountain bike chain, we've got the leading component brands to choose from including SRAM and Shimano, with further details on what to consider in our bike chain buyers guide.
When replacing a bike chain, be sure to also inspect the cassette's condition, as a new chain might slip on a worn cassette.
