The Shimano CN-HG701-11 11-speed chain in 126 maillons is a high-performance chain designed for 11-speed road bike, mountain bike and e-bike drivetrains. Part of the Shimano range, compatible with Ultegra and Deore XT drivetrains, it combines a directional design, SIL-TEC surface treatment and a reinforced structure to deliver smooth, quiet and durable performance.

Part number ICNHG70111126Q, this Shimano chain is particularly well-suited to cyclists seeking a precise and reliable drivetrain, both on the road and off-road. Shimano It is specifically designed for road bikes, mountain bikes and e-bikes fitted with a compatible 11-speed drivetrain.

A versatile 11-speed Shimano chain

The CN-HG701-11 is a directional chain developed for Shimano 11-speed drivetrains. Its design optimises the chain’s performance during gear changes to ensure smoother and more reliable shifting.

It is an excellent choice for many Shimano drivetrains – including Ultegra, 105, Dura-Ace, Deore XT and SLX – as well as other compatible 11-speed set-ups, provided the compatibility chart at Shimano is followed.

The documentation at Shimano specifically confirms the compatibility of the CN-HG701-11 with several road, gravel and MTB drivetrains, as well as 1x11 configurations.

SIL-TEC treatment: reduced friction and increased durability

The CN-HG701-11 chain features SIL-TEC treatment on both the inner and outer plates. This ultra-low-friction surface treatment improves the chain’s performance whilst contributing to its durability.

According to Shimano, SIL-TEC is a sophisticated surface treatment process that enables treated components to operate more smoothly and maintain their performance for longer, even under varied riding conditions.

For cyclists, this translates into, in particular, a quieter drivetrain, smoother operation and a more consistent gear-changing feel.

A reinforced chain for mountain bikes and e-bikes

The CN-HG701-11 is not limited to road use. Its reinforced design also makes it suitable for use on 11-speed mountain bikes and compatible 11-speed e-bikes.

Shimano It is specified that the chain is reinforced to better withstand the stresses associated with electric-assisted riding. It is officially listed as compatible with e-bike rear derailleur systems.

It is therefore particularly suitable for riders looking for a versatile 11-speed chain for a road bike, gravel bike, mountain bike or e-bike.

QUICK-LINK: easy fitting

This version of the CN-HG701-11 comes with a QUICK-LINK, making it easy to connect the chain.

The QUICK-LINK system Shimano allows for convenient installation and can be fitted without tools in certain situations, whilst Shimano recommends using its specialised pliers to ensure the chain is fitted and removed correctly.

When fitting, it is essential to follow the direction of the chain and to ensure that the QUICK-LINK is correctly locked before use.

126 maillons: a length suitable for a wide range of set-ups

With 126 maillons, this chain offers a generous length, making it suitable for various 11-speed drivetrain set-ups.

Please note, however, that the number of links required does not depend solely on the number of gears. The final length must be determined based on the type of bike, the size of the chainring and cassette, the chainstay length and the derailleur configuration.

Shimano points out that there is no one-size-fits-all length for all bikes and recommends determining the exact chain length before fitting.

The CN-HG701-11 is particularly appealing for its balance of performance, reliability and versatility. It boasts a higher standard of finish than a basic 11-speed chain, thanks in particular to the SIL-TEC treatment and its reinforced design.

On a road bike, it offers smooth and quiet operation, with precise gear changes. On a mountain bike, its directional design and durability make it a solution perfectly suited to regular off-road use.

For an 11-speed e-bike, its benefits are even more pronounced: Shimano has specifically reinforced this chain to withstand the additional stresses associated with electric assistance.

Expert tip: don’t choose a chain based solely on the number of speeds. Always check that it’s compatible with your entire drivetrain. When replacing it, also check the condition of the cassette and the chainring(s). A new chain fitted to a heavily worn drivetrain can cause the chain to jump and accelerate wear.

To maximise the lifespan of your drivetrain, clean the chain regularly and use a lubricant suitable for your riding conditions.
