The Shimano CUES ST-U3030 brings the ergonomic feel of Shimano's higher-grade mechanical dual control levers to everyday road and gravel riding. This is the right-side lever for a 9-speed mechanical disc brake setup, pairing crisp, intuitive shifting with comfortable, controlled braking in a single unit.

Highlights

• Right-side dual control lever for 9-speed Shimano CUES drivetrains
• Operates a cable-actuated (mechanical) disc brake caliper
• New Super SLR short-pull braking for smooth response and modulation
• Tool-free reach adjustment to suit a range of hand sizes
• Ergonomic lever shape inherited from Shimano's premium dual control levers

Comfortable, confident control

The lever body is shaped to fit hands of all sizes, giving a secure, natural grip whether you are riding on the hoods or braking from the drops. Reach adjustment lets you bring the lever closer for smaller hands or longer rides.

Smooth mechanical braking

Shimano's New Super SLR short-pull design reduces friction through the lever and cable, so braking feels light and progressive. It is built to drive a cable-operated disc brake caliper for reliable, low-maintenance stopping power.

Compatibility & fit

This is the right-hand lever. In the standard Australian setup the right lever operates the front brake, and the right lever also controls rear-derailleur shifting across a 9-speed Shimano CUES cassette. Use with a mechanical (cable-actuated) disc brake caliper, which is sold separately. Designed to integrate with Shimano CUES 9-speed (LINKGLIDE) drivetrain components. Not compatible with hydraulic disc brakes.
