The Shimano Tiagra CN-4601 10-speed chain, item number ECN4601116, is a super-narrow HG chain designed for 10-speed bicycle drivetrains. Reliable, precise and durable, it is an excellent choice for replacing a worn chain on a road bike fitted with a 10-speed Shimano drivetrain.

With its 116 links, directional design and Hyperglide (HG) technology, the CN-4601 enables fast and precise gear changes whilst ensuring efficient transfer of pedalling power. Shimano has included it in its SELECT performance range.

A reliable and high-performance Shimano 10-speed chain

The CN-4601 is specially designed for Shimano Tiagra drivetrains from the 4600 series. Its directional design utilises optimised inner and outer plates to improve engagement with the teeth of the chainrings and sprockets.

This architecture helps to ensure smooth and precise gear changes, even under load. The outer plates are specifically designed to minimise the risk of chainsuck, whilst the inner plates ensure efficient shifting across the cassette.

The chain comes with a connecting pin ( Shimano ), allowing it to be fitted once its length has been adjusted to suit the bike.

A chain designed for a 10-speed drivetrain

The Shimano CN-4601 is particularly well-suited to road bikes fitted with a 2x10-speed drivetrain, notably those featuring Shimano r Tiagra 4600 components. It is designed to work with compatible 10-speed Shimano systems and offers a good balance between shifting precision, efficiency and durability.

Its directional design is important: the chain must be fitted the correct way round to fully benefit from the performance specified by Shimano. Markings on the chain help you identify the outer side during installation.

Expert tip: do not choose a chain based solely on the number of gears. Also check the type of drivetrain, component compatibility and the required length. When fitting the CN-4601, it is essential to follow the fitting direction specified by Shimano.

You should also take the opportunity during replacement to check the condition of the cassette and chainrings. A heavily worn chain can accelerate their wear and tear.
