A precise and reliable 11-speed rear derailleur for road bikes

The Shimano 105 RD-R7000-SS is a mechanical 11-speed rear derailleur with a short cage, designed for road bike drivetrains Shimano. Part number IRDR7000SSL, this black version features SHIMANO SHADOW RD technology, which prioritises a low profile and excellent shifting stability.

Intended for 2x11-speed drivetrains, the RD-R7000-SS accommodates a cassette of up to 30 teeth. It is therefore an excellent choice for replacing a worn Shimano 105 R7000 rear derailleur or for building a complete 11-speed setup.

Its precise mechanical operation, robust design and relatively simple adjustment make it a particularly attractive option for both everyday training and competitive road cycling.

Shimano Shadow RD technology

The SHIMANO SHADOW RD is a low-profile rear derailleur design developed to improve the stability of the mechanism.

By reducing the overhang of the derailleur relative to the frame, this design notably limits its exposure to impacts and helps maintain a stable chain path.

On the RD-R7000-SS, this design is combined with a rigid structure and a gear-changing capacity suited to 11-speed road drivetrains. Shimano thus delivers stable gear-changing performance.

A short cage suitable for cassettes with up to 30 teeth

The choice between the RD-R7000-SS and the RD-R7000-GS depends mainly on the cassette used.

The SS version with a short cage accommodates sprockets ranging from 25 to a maximum of 30 teeth, with a total capacity of 35 teeth.

It is therefore particularly well-suited to classic road set-ups such as:

• 11-25;
• 11–28;
• 11-30.

For an 11-32 or 11-34 cassette, it is best to choose the GS version with a medium cage, designed for a wider gear range.

An ideal solution for a Shimano 105 11-speed drivetrain

The RD-R7000-SS fits seamlessly into a mechanical Shimano 105 R7000 drivetrain. It can also be used with compatible 11-speed Shimano road components.

In particular, it is designed to work with Shimano 11-speed chains and cassettes suitable for this generation of drivetrain. Shimano indicates compatibility with HG 11-speed chains.

The inclusion of a cable tension adjuster directly on the derailleur also makes adjustment easier and ensures precise shifting.

RD-R7000-SS or RD-R7000-GS?

The choice is simple:

The SS version is therefore particularly suitable for drivetrains with 11-25, 11-28 or 11-30 cassettes. For a cassette with a large 32- or 34-tooth cog, the GS version is recommended.

When should you replace your rear derailleur?

The entire derailleur does not necessarily need replacing as soon as gear changes become imprecise. Incorrect adjustment, a bent derailleur hanger or worn cables may be the cause of the problem.

However, replacing the RD-R7000-SS may be advisable in the following cases:

• damage to the derailleur following a fall;
• a bent derailleur hanger;
• a severely damaged derailleur body;
• excessive mechanical play;
• a faulty spring or internal mechanism;
• significant corrosion;
• inability to achieve correct adjustment despite the drivetrain being in good condition.
