Smooth and Precise Hyperglide Shifting
Shimano HG-EV technology uses specially designed sprocket profiles to guide the chain smoothly between gears.
When paired with compatible Shimano shifters, derailleurs and chains, the CS-R7000 provides responsive shifting for training, recreational riding and longer road adventures.
Balanced 11-30T Gearing
The 11-30T configuration offers a balance between closely spaced ratios and climbing capability.
Its eleven sprockets are arranged as follows:
11 – 12 – 13 – 14 – 15 – 17 – 19 – 21 – 24 – 27 – 30T
The closely spaced smaller sprockets help riders fine-tune their cadence on faster sections, while the 30-tooth largest sprocket provides an easier gear for hills.
Compatibility
The CS-R7000 requires a compatible Shimano HG road 11-speed freehub body and an appropriate 11-speed drivetrain.
For Shimano 105 R7000 rear derailleurs, the 11-30T configuration is supported by both RD-R7000-SS and RD-R7000-GS, subject to the complete drivetrain's capacity requirements.
Before installation, confirm the rear derailleur's supported sprocket range, total capacity and chain compatibility.
This cassette does not fit Shimano Micro Spline freehub bodies or threaded freewheel hubs.
Installation and Maintenance
Use appropriate cassette installation tools and follow Shimano's recommended lockring tightening torque.
Inspect chain wear when replacing the cassette to preserve smooth shifting and drivetrain performance.
Note: This product is the Shimano 105 CS-R7000 cassette in the 11-30T configuration.
