SRAM Rival AXS D1 12-Speed 2x DUB Quarq Power Meter Crankset

The SRAM Rival AXS D1 crankset with Quarq power integrates a spindle-based power meter into a 12-speed aluminum double. SRAM's DUB-PWR unit sits entirely inside the DUB spindle, so the crank installs like a standard Rival AXS crankset.

This listing offers 175mm arms in 46/33T or 48/35T, and 172.5mm arms in 46/33T. Power is measured on the left side and doubled to calculate total watts. The DUB bottom bracket is not included.

Who It's For

• Road riders on SRAM AXS 12-speed 2x drivetrains who want power data
• Riders who prefer a crank-based meter that keeps any pedals
• Riders comfortable with left-side measurement
• Consider a different crank if you need independent left/right power or a length other than 172.5 or 175mm

What to Look For

• Spindle interface: SRAM DUB (DUB-PWR spindle). The bottom bracket is sold separately.
• Length and rings: 175mm comes in 46/33T or 48/35T; 172.5mm is offered in 46/33T.
• Measurement: left-side spindle power, doubled for total watts; ANT+ and Bluetooth LE.

Key Features

DUB-PWR spindle meter. The power unit is contained in the DUB spindle and measures left-side power. It runs on a user-replaceable AAA lithium battery rated for 400+ hours and is IPX7 waterproof to 1 meter for 30 minutes. SRAM states it adds less than 40g over a standard crankset.

Aluminum arms on DUB. The aluminum arms use the SRAM DUB spindle standard with a 28.99mm spindle diameter. Choose a DUB bottom bracket for your frame; it is sold separately.

107 BCD double. The 12-speed double rings sit on a 107 BCD with a 45mm chainline, the road stance for SRAM's AXS 2x groups.

Connectivity and finish. ANT+ and Bluetooth LE let the meter pair with most head units. Black finish, 9/16" pedal threads.

Rider Intent Summary

• Biggest strengths: Crank-based power that keeps the clean look of a standard Rival AXS crank.
• Tradeoffs: Left-side measurement only; limited length and ring combinations; bottom bracket sold separately.
• What makes it different: The whole power unit is inside the spindle rather than in a spider or pedal.

Victory's Take

At Victory Bicycle Studio we often recommend this as a first power meter for AXS road bikes, and we set riders' expectations on left-only data. We can check which length and ring combination suits your fit before you order.
