Wireless SRAM X0 Eagle Transmission Groupset for High-Performance E-MTB Riding
The SRAM X0 T-Type Eagle E-MTB Transmission AXS Groupset 104BCD is a rugged, high-performance wireless drivetrain package engineered for the demands of modern electric mountain bikes.
Developed as part of SRAM’s Eagle Transmission platform, the X0 system brings the derailleur, cassette, chain and AXS controls together as one integrated drivetrain. The result is smooth, stable and precise shifting designed to perform even under the increased torque generated by powerful e-MTB motors.
At the heart of the system is the X0 Eagle AXS T-Type rear derailleur, combined with the wide-range XS-1295 10-52T cassette, an e-MTB-approved X0 Flattop chain and the premium AXS Pod Ultimate controller.
This 104BCD version is supplied without crank arms, making it ideal for compatible e-MTB setups where the existing or separately selected crankset is retained.
Designed for E-MTB Transmission Performance
Electric mountain bikes place significantly greater loads on drivetrain components than conventional bikes. The X0 Eagle Transmission system is designed around these demands, providing increased stability and dependable shifting for aggressive trail and enduro e-MTB riding.
Rather than treating individual components separately, SRAM’s Transmission platform is engineered as an integrated system so the cassette, derailleur and chain work together.
Shifting Under Load
One of the defining advantages of SRAM Eagle Transmission is its ability to shift cleanly while the drivetrain is under substantial load. The X0 cassette combines X-SYNC technology with precisely engineered cassette mapping to control where and how the chain moves between sprockets.
This enables smooth and consistent gear changes even when significant torque is being delivered by both rider and motor.
X0 Eagle AXS T-Type Rear Derailleur
The included X0 Eagle AXS T-Type rear derailleur delivers wireless electronic shifting as part of SRAM’s integrated Transmission platform. Designed for demanding off-road conditions, it forms the centre of the drivetrain and communicates with the AXS controller for fast, precise gear selection without conventional shift cables.
XS-1295 T-Type 10-52T Cassette
The groupset includes SRAM’s X0 XS-1295 Eagle Transmission cassette with a wide 10-52T gear range. This gives e-MTB riders the range required for steep technical climbing while retaining a small 10-tooth sprocket for faster terrain.
The cassette’s shift architecture is specifically designed to work with the T-Type chain and derailleur as a complete system.
X0 Transmission Flattop Chain
The included X0 Eagle Transmission Flattop Chain is built for the additional demands of electric mountain biking.
It features:
- Dark Polar finish exclusive to X0
- Electroless nickel plating
- PVD surface treatment
- Solid pins
Full E-MTB approval
The combination of coatings is designed to improve wear and corrosion resistance, while the solid-pin construction provides the strength required for high-output electric drivetrains.
AXS Pod Ultimate Controller
Shifting is controlled through the included AXS Pod Ultimate. Its compact two-button “click and fire” design provides intuitive control while allowing the rider to personalise button functions through the AXS ecosystem. The Concave Pod configuration provides a shaped contact surface designed for precise control on demanding terrain.
Wireless AXS Operation
As an AXS electronic drivetrain, the system removes the need for a conventional mechanical shift cable. Wireless control helps create a cleaner cockpit while also providing precise electronic gear changes.
The groupset includes both an AXS battery and charger, providing the essential power components needed for the derailleur system.
104BCD E-MTB Configuration
This version is identified as the 104BCD configuration, making it suitable for compatible e-MTB chainring and crank interfaces using that mounting standard.
Always confirm motor, crank, chainring and frame compatibility before installation.
Aeroguard Included
The supplied specification includes an Aeroguard, providing additional protection around the chainring area on compatible installations.
The wider X0 e-MTB platform also supports bashguard configurations for increased protection when riding rocky or technical terrain.
Cranks Not Included
Please note that crank arms are not included with this groupset.
Although SRAM’s wider X0 Eagle Transmission e-MTB range includes compatible Bosch and Brose crank options, this 104BCD groupset should be paired with the correct separately supplied crank and chainring arrangement for your bike.
Designed for Enduro and Aggressive E-MTB Riding
The SRAM X0 Eagle Transmission groupset is particularly well suited to enduro e-MTB, trail e-MTB, aggressive electric mountain biking, high-torque motor systems, technical climbing, long-distance trail riding and SRAM Transmission upgrades.
