Chains

Bike chains are speed-specific, meaning they are designed to work with a drivetrain that has a matching number of rear sprockets. To find the right chain, count the sprockets on your rear cassette and match that number to the chain specification. Using an incompatible chain can cause poor shifting, skipping, or premature wear on your cassette and chainrings.

A standard replacement chain is designed to restore your drivetrain to working condition and suits everyday riders focused on reliability and value. Performance chains typically feature advanced coatings, precision construction, or hollow pins that reduce friction and extend the chain's lifespan. If you ride frequently or competitively, a performance chain can improve shifting quality and reduce drivetrain wear over time.

Chains wear gradually through use and stretch over time, which can cause poor shifting and accelerated wear on your cassette and chainrings. A chain wear indicator tool is the most reliable way to measure stretch and determine whether replacement is needed. Replacing a chain at the right time is one of the most cost-effective ways to extend the life of your entire drivetrain.

When building or rebuilding a drivetrain, the chain must be matched to the speed configuration of your cassette, chainring, and shifters to ensure everything works together correctly. It is also worth considering the brand ecosystem of your components, as some drivetrains are optimised to perform best with chains from the same manufacturer. Choosing a chain that suits your intended riding style, whether that is commuting, trail riding, or road cycling, will help you get the best performance from your build.

No, 13-speed chains are designed specifically for 13-speed drivetrains and are not compatible with older speed configurations. The narrower width and specific tolerances of a 13-speed chain mean it will not shift correctly or seat properly on cassettes and chainrings designed for fewer speeds. Always match your chain to the exact speed specification of your drivetrain to avoid compatibility issues
