Shimano CUES CS-LG300-10

While it is engineered specifically to handle the high torque of e-bike motors, it is fully compatible with standard mountain bikes as well. It is an excellent choice for any rider prioritizing long-term durability and smooth shifting over lightweight performance.

LINKGLIDE technology uses a more robust tooth profile to increase the surface contact area, which helps the chain move more smoothly between gears. This design significantly reduces wear and tear, offering up to three times the durability of standard cassettes, especially under the heavy load of an e-bike motor.

The CS-LG300-10 is compatible with standard Shimano/SRAM 8, 9, and 10-speed freehub bodies. If your current wheelset uses a standard HG-style freehub, this cassette will install without any modifications.

No, the cogs on this model are not individually removable. Because the cassette is designed as a single, durable unit to handle high-torque shifting, you will need to replace the entire cassette once the teeth have reached the end of their lifespan.

You will notice that shifting feels slightly more deliberate and smoother, particularly when shifting under load. The LINKGLIDE system is designed to reduce the 'clunk' or pedal impact often felt when changing gears while climbing or accelerating.

At 725 grams, this is a heavy-duty component built for longevity rather than weight savings. If you are looking to build the lightest possible race bike, this is likely not the right choice, but if you want a drivetrain that resists wear over thousands of miles, the extra weight is a worthwhile trade-off.
