Shimano Ultegra 6700

The Ultegra 6700 is designed for standard 10-speed Shimano road drivetrains. As long as your shifters, derailleur, and chain are compatible with the Shimano 10-speed ecosystem, this cassette will integrate seamlessly.

No, the lockring is not included with this cassette. You will need to reuse your existing lockring or purchase a compatible Shimano-standard lockring separately to secure the cassette to your freehub body.

No, the cogs on this cassette are not individually removable. Because the design uses a rigid alloy carrier to reduce weight, the cassette functions as a single unit, meaning you will need to replace the entire cassette once the teeth show significant wear.

The alloy carrier is engineered to provide a rigid platform that reduces weight without compromising the structural integrity of the drivetrain. While it is lighter than steel-only alternatives, it remains highly durable and is specifically built to handle the high-load conditions of competitive road cycling.

Shimano's Hyperglide technology uses specific tooth profiling and ramp designs to guide the chain smoothly between cogs. This ensures that your gear transitions remain crisp and reliable, even when you are shifting under the pressure of a climb or a sprint.
