SRAM XS-1275 12-speed T-Type Cassette for GX Eagle Transmission

The XS-1275 T-Type cassette from SRAM for a 12-speed drivetrain with GX Eagle Transmission

The SRAM XS-1275 T-Type cassette is particularly recommended for a 12-speed mountain bike drivetrain in combination with other components from the robust entry-level GX Eagle Transmission series. Due to its robustness, it is also suited for e-bikes. The smallest sprockets are manufactured in one piece as a mini cluster, the remaining sprockets are assembled in a pindome design. Compared to Eagle cassettes, the gear gradation of the largest sprockets is more even. The X-Sync design enables outstanding shifting performance even and especially under full load. Thanks to cassette mapping, the gear changes take place along designated shift ramps, which makes the process extremely smooth. With a chainline of 55 mm, the lower chain angle is noticeable, which reduces wear and increases precision. The cassette can only be used together with an Eagle Transmission rear derailleur, with which it opens up an ideal shifting experience. As an assembly aid, the setup sprocket that you need for the correct adjustment of the rear derailleur is highlighted in colour.

Guidelines for Replacing E-bike Components:

Before you replace components on your e-bike, please read through the guidelines for component replacement for CE-marked e-bikes/pedelecs with pedal assistance.

GX Eagle Transmission 12-speed

Compatibility:

• only compatible with Eagle Transmission rear derailleurs

Features:

• robust, inexpensive 12-speed cassette for an electronic mountain bike drivetrain
• largest sprocket made of aluminium, others made of steel
• smallest sprockets as one-piece mini cluster, others in pindome design
• excellent shifting performance under full load thanks to X-Sync design
• more consistent gear sequence than Eagle with regard to the largest three sprockets
• in conjunction with 55 mm chainline, more moderate chain angle, thus higher resistance and precision
• forms a functional unit with Eagle Transmission rear derailleur
• setup sprocket colour-coded for correct derailleur setting
• cassette mapping for smooth shifting along designated shift ramps
• also suitable for e-bikes

Technology:

MINI CLUSTER™
MINI CLUSTER refers to a hybrid construction resulting in a light and strong cassette: The smallest sprockets are CNC-machined from a single block of steel, while the other sprockets are assembled with pins. This saves weight and ensures fast, precise shifting.

X-Sync™
The X-Sync tooth design is characterised by long, rounded and slanted tooth edges with a narrow profile. Derailleur pulleys with X-Sync technology support the chain guide and remain unaffected by dust and mud.
