The Shimano CS-M8000 is an 11-speed cassette from the Deore XT series, designed for mountain bikes. The 19-tooth sprocket variant is an intermediate sprocket that is among the most common combinations in 11-speed cassettes.

Features of the 19-tooth sprocket (CS-M8000):

• Compatibility: Shimano Deore XT M8000 cassette (11-speed).
• Number of teeth: 19 teeth, one of the intermediate sprockets in a typical cassette configuration.
• Sprocket position: The 19-tooth sprocket is typically used in configurations such as 11–46 teeth or 11–42 teeth, where it provides a good compromise between road and climbing performance.
• Material: Made from treated steel for durability and wear resistance, with a treated surface to enhance corrosion protection.
• Technology: Utilizes Hyperglide technology to improve shifting by reducing friction and enhancing smoothness during under-load shifting.
• Design: Multi-sprocket construction (starting with the largest sprocket) to reduce overall weight and improve cassette stiffness.
• Replacement and compatibility: The 19-tooth sprocket can be replaced individually or as part of a complete cassette. It is important to check compatibility with the chain and derailleur. Shimano M8000 cassettes are fundamentally designed for use with 11-speed derailleurs, so it is essential to ensure that the entire group is compatible.

Some benefits: Precise shifting thanks to Hyperglide technology. Longer lifespan than other components due to high-quality materials.
