Shimano DEORE XT CS-M8100 12-speed Cassette

The Shimano DEORE XT CS-M8100 12-speed cassette is designed to offer high shifting performance, lightweight, and a wide gear range for mountain biking. Thanks to the combination of HYPERGLIDE+, BEAM SPIDER, and MICRO SPLINE technologies, this cassette ensures fast and smooth gear changes, increased chain stability, and efficient drivetrain management.

The BEAM SPIDER structure allows for a lighter and stiffer cassette, reducing inertia and promoting faster acceleration. The increased stiffness also contributes to improved chain stability during pedaling and on more challenging terrains.

HYPERGLIDE+ technology, thanks to new guide profiles, enables faster and smoother shifts, promoting continuous pedaling even when shifting between gears.

The MICRO SPLINE system, on the other hand, allows for the use of a smaller 10-tooth sprocket, increasing the available range and enabling a 12-speed MTB drivetrain with close-ratio and wide-range gears.

The Shimano DEORE XT CS-M8100 is available in 10-45T and 10-51T configurations, to suit different riding needs and terrain types.

Shimano Technologies

HYPERGLIDE+

HYPERGLIDE+ technology is designed to offer excellent shifting performance. New guide profiles promote faster and smoother gear changes, improving pedaling continuity during shifts.

This technology helps to make the drivetrain more responsive and precise, a particularly important feature during MTB riding, when it is necessary to quickly change gears based on the slope and terrain.

Benefits of HYPERGLIDE+

• New guide profiles
• Faster shifts
• Smoother shifts
• Greater pedaling continuity
• High shifting performance

BEAM SPIDER

The BEAM SPIDER structure allows for a cassette that is characterized by an excellent balance between reduced weight and stiffness.

The lighter structure helps to reduce the cassette's inertia, promoting faster acceleration. The increased stiffness also helps maintain better chain stability during pedaling.

Benefits of BEAM SPIDER

• Lighter structure
• Increased stiffness
• Reduced cassette inertia
• Faster acceleration
• Increased chain stability

MICRO SPLINE

The MICRO SPLINE system uses the new Shimano rear freehub body standard and allows for the use of a 10-tooth sprocket.

The presence of the 10T gear allows for expanding the drivetrain's range, while maintaining a compact 12-speed configuration.

Benefits of MICRO SPLINE

• Compatibility with Shimano MICRO SPLINE rear freehub body
• Smaller 10T sprocket
• Wider gear range
• 12-speed configuration
• Ideal for wide-range MTB drivetrains

Available Configurations

The Shimano DEORE XT CS-M8100 is available in two configurations:

10-45T

The 10-45T configuration offers a wide range with closer ratios, ideal for those seeking precise cadence management and progressive gear changes during MTB riding.

10-51T

The 10-51T configuration offers an even wider range, with a maximum 51-tooth gear particularly suitable for tackling challenging climbs and routes with high gradient variations.
