Description

The SRAM XS-1297 T-Type Eagle 10-52T cassette is the premium XX Eagle Transmission cassette, engineered specifically for SRAM's Eagle Transmission drivetrain.

Designed to deliver precise shifting under load, the XS-1297 combines a huge 520% gear range with SRAM's full X-SYNC design and X-DOME cassette technology.

With a 10T smallest sprocket and 52T largest sprocket, this 12-speed cassette provides the high gearing needed for fast sections while giving you the low-end range required for steep and technical climbs.

Finished in Black, the XS-1297 is designed for compatible SRAM Eagle Transmission (T-Type) 1x12 drivetrains and uses an XD driver body.

The XS-1297 is designed as part of the SRAM Eagle Transmission system, where the cassette and rear derailleur work together as integrated drivetrain components.

Its 10-52T range provides a massive 520% spread between the highest and lowest gears, giving riders plenty of range for both high-speed riding and demanding climbs.

The cassette uses an updated gear progression compared with the traditional Eagle 10-52T cassette, with additional low-end steps through the 38T and 44T sprockets before reaching the 52T largest sprocket.

12-Speed Gear Range

The XS-1297 uses the following sprocket progression:

10T – 12T – 14T – 16T – 18T – 21T – 24T – 28T – 32T – 38T – 44T – 52T

The wide range makes the cassette suitable for modern mountain bikes where a single chainring drivetrain needs to provide both efficient high-speed gearing and substantial climbing capability.
