The SRAM XG-1275 Eagle S200 12V Cassette featured here at Escapa is a 12-speed cassette designed for MTBs with a single-chainring drivetrain. Available in 10-50T and 10-52T gear ratios, it offers a 500% or 520% range to combine speed on rolling terrain with short gear ratios capable of tackling steep climbs.
Its FULL PIN construction uses precision-machined steel sprockets, joined by high-strength stainless steel pins. The result is a robust, durable cassette built to maintain reliable performance during long rides and demanding mountain biking sessions.
10-50T and 10-52T Versions
The SRAM XG-1275 is available in two gear ranges:
- 10-50T: offers a total range of 500%.
- 10-52T: extends the range to 520% and provides an even lower gear for steep climbs.
The 10-50T version features the following tooth count progression: 10-12-14-16-18-21-24-28-32-36-42-50T.
The 10-52T version uses this gear sequence: 10-12-14-16-18-21-24-28-32-36-42-52T.
The small 10-tooth chainring allows you to reach good speeds on trails and descents, while the 50- or 52-tooth chainrings make it easier to maintain an efficient cadence as the slope increases.
FULL PIN Technology
FULL PIN technology connects the steel sprockets using stainless steel pins. This construction creates a durable and relatively lightweight assembly, designed to withstand the forces of a wide-range MTB drivetrain.
The open design, inspired by SRAM’s X-DOME cassettes, facilitates the removal of mud and debris. This helps maintain shifting precision and reduces the buildup of debris between the sprockets.
Compatible with SRAM XD Freehub Body
The XG-1275 uses an SRAM XD freehub body, which is required to install the 10-tooth small chainring. It is not directly compatible with Shimano HG or SRAM XDR freehub bodies without the appropriate adapters or configurations.
Integration with Eagle Drivetrains
This cassette is designed for SRAM Eagle 1x12 drivetrains and must be used with a compatible Eagle chain. Its sprocket spacing allows for smooth shifting between sprockets, maintaining a wide gear range without the need for a front derailleur.
