Product Description
The SRAM XX SL Eagle T-Type AXS Transmission Power Meter Groupset represents the pinnacle of SRAM’s cross-country drivetrain technology. Developed for riders who prioritize race-level weight, precise wireless shifting, accurate power data, and dependable performance under load, XX SL Transmission brings together SRAM’s lightest T-Type components in one premium package.
Unlike a traditional derailleur system, the XX SL Eagle Transmission rear derailleur uses SRAM’s Full Mount hangerless interface, attaching around the wheel axle on compatible UDH-equipped frames. This creates a stronger, more precise connection between the derailleur, cassette, and frame while eliminating traditional limit screws and derailleur-hanger adjustment.
The included XX SL carbon crankset features a spider-based power meter that measures total rider power and transmits live data to a compatible cycling computer. A 34T T-Type thread-mount chainring, ultra-lightweight XS-1299 10-52T cassette, XX SL FlatTop chain, AXS Pod Ultimate controller, derailleur battery, and charger complete the system.
This is a multi-variation listing. Select either the 170mm or 175mm crank length. All other included components and specifications remain the same.
All components are brand new and retail packaged.

Compatibility
This groupset is designed for compatible mountain bikes requiring:
- A frame approved for SRAM Eagle Transmission
- SRAM Universal Derailleur Hanger-compatible frame interface
- Compatible Full Mount rear derailleur installation

Important T-Type Compatibility
SRAM Eagle Transmission is an integrated system. T-Type components should not automatically be treated as interchangeable with standard Eagle mechanical or Eagle AXS drivetrain parts.
The frame must support SRAM’s Full Mount hangerless derailleur interface. Having a replaceable derailleur hanger alone does not confirm compatibility.
Bottom Bracket
A bottom bracket is not included. All SRAM DUB cranksets require a compatible SRAM DUB bottom bracket selected for the bicycle frame’s specific bottom bracket shell standard.
Please confirm frame compatibility, crank length, bottom bracket standard, chainline, cassette driver, and component requirements before purchase.
