SRAM RED AXS D1 Power Meter Crankset 175mm 46/33T DUB 12-Speed Carbon

Product Description
The SRAM RED AXS D1 Power Meter Crankset combines ultra-light hollow carbon crank arms, integrated Quarq power measurement, and SRAM X-Range 46/33T gearing in a premium 2x road drivetrain package.
This 175mm configuration uses a 46/33T integrated aluminum chainring and power meter assembly, standard Road DUB spindle, and 45mm chainline. The consistent 13-tooth difference between the front chainrings is designed for fast, precise front shifting across compatible SRAM AXS road drivetrains.
The Quarq power meter measures power from both sides, provides left/right power balance, and communicates through ANT+ and Bluetooth.
These are genuine SRAM OEM components sourced directly from SRAM, supplied without retail packaging, and covered by the full applicable SRAM manufacturer warranty.

D1 Power Meter Design
The RED AXS D1 system integrates the power meter directly into the one-piece 2x chainring assembly. This design reduces weight and increases chainring stiffness while allowing Quarq to measure total power and left/right balance at the spider.
Because the power meter and chainrings are integrated, replacing worn chainrings requires replacement of the compatible integrated power meter/chainring assembly rather than changing individual rings.
D1 / D2 / E1 Drivetrain Compatibility
Although this is a D1-generation RED AXS crankset, it remains compatible with current SRAM AXS road drivetrain technology.
It can be used with appropriate:
SRAM Road Flattop D1 chains
SRAM Road Flattop E1 chains
D1-generation SRAM AXS road components
D2-generation compatible AXS road components
Current E1-generation AXS road components
SRAM's current compatibility information continues to support the 46/33T D1 RED power meter alongside newer AXS road front derailleurs and Flattop chains.
The D1 designation primarily identifies the crankset generation and correct replacement parts. It does not mean the crankset is limited to a complete D1-only drivetrain.
Compatibility
Designed for compatible road bikes using:
SRAM AXS 2x road drivetrain
46/33T X-Range gearing
Standard SRAM Road DUB bottom bracket
45mm chainline
SRAM Road Flattop chain
This is the standard Road DUB version, not a DUB Wide crankset.
Confirm bottom bracket standard, front derailleur compatibility, chainline, crank length, and frame clearance before ordering.
