Train and race on accurate, repeatable power data from SRAM's lightest road cranks. The RED AXS D1 power meter crankset measures both legs at the spider, so every watt is captured without sacrificing the stiffness and weight of the latest RED carbon arms. This is the 175mm length with 46/33T chainrings.
Highlights
- Dual-sided power, accurate within +/-1.5% and unaffected by changing weather
- 175mm crank arm length with a 46/33T chainring combination
- Hollow carbon crank arms - SRAM's lightest road cranks
- DUB spindle interface fits all SRAM road DUB bottom brackets
- Dual ANT+ and Bluetooth SMART for head units, watches and training apps
- User-replaceable CR2032 coin-cell battery
Measure both legs, train smarter
The power meter is built into the crank spider and reads left and right leg power independently, giving you a true left/right balance alongside total output. Accuracy is held to +/-1.5% and is not affected by temperature or climate during a ride, so your numbers stay consistent from cold starts to long climbs.
Light, stiff carbon cranks
Hollow carbon crank arms keep the package light and rigid for efficient power transfer. The 46/33T chainrings sit on a direct-mount 8-bolt interface as an integrated unit and run a 13-tooth jump between rings for predictable front shifts across SRAM's X-Range gearing.
Connectivity and power
Dual ANT+ and Bluetooth SMART let the crankset pair with virtually any cycling computer, smartwatch or indoor trainer app. A user-replaceable CR2032 coin-cell battery keeps maintenance simple.
Compatibility and fit
Designed for 12-speed SRAM RED AXS 2x road drivetrains. The DUB spindle is compatible with all SRAM road DUB bottom brackets (frame-specific DUB BB sold separately). Chainline is 45.0mm with a 145mm Q-factor. Choose this 175mm option to match your existing crank length and fit. If you are unsure of the correct length or bottom bracket standard for your frame, our workshop can help.
