Sram Quarq Force AXS Power Meter PWR Left Crank Arm:

Proven reliability and accuracy from Quarq. The new power meter platform is fully integrated into the DUB spindle. The spindle-based DUB-PWR unit measures power on the left side to calculate total watts. The long battery life, over 400 hours, ensures a full season of riding. Waterproof, IPX7 rated to 1 metre for 30 minutes, and lightweight, weighing less than 40 g more than a standard crankset. The SRAM Rival AXS aluminium crankset for the new AXS groupset, in combination with the new 12-speed cassette, offers a completely new gear ratio range. The smaller chainrings and the cassette with a wider range offer a greater gear range than previous systems. The result is smoother and faster front shifting and more usable gears. The new configurations this enables improve cadence and efficiency and ensure crisp, clean and fast gear changes. With conventional chainring/cassette combinations, the overall range is smaller; for example, a 53-tooth chainring with an 11-tooth sprocket gives a gear ratio of 1:4.81. With the new combinations featuring a 48-tooth chainring and a 10-tooth sprocket, the ratio is 1:4.8. Furthermore, a 1:1 gear ratio is possible with a 33-tooth sprocket at the front and rear.

SRAM DUB Axle and Bottom Bracket System:

The DUB version of the SRAM cranksets is suitable for BSA threaded, PressFit BB92, PressFit 30, BB30, BB386 Evo BB Right and T47 bottom bracket shells. You will find the compatible bottom brackets listed below with their installation dimensions. The axles have a diameter of 29 mm. Axle play is adjustable via a preloader. The SRAM DUB road bike cranksets have a completely proprietary standard and are only compatible with DUB road bike bottom brackets, not with other bottom brackets. SRAM and Wheels Manufacturing offer compatible bottom brackets for almost every bottom bracket standard; only bottom brackets for Italian thread and Trek BB90 are not available. In those cases, GXP crank arms are required.
