Powermeter cranksets put your training data right at the source—no secondary sensors, no estimation algorithms, just direct strain gauge measurement where you're actually producing watts. The Force AXS E1 DUB Power Meter Crankset from SRAM integrates their Quarq power measurement into the hollow carbon crankarms, capturing left and right leg data independently for power balance metrics alongside total output.

The E1 designation indicates SRAM's current-generation power meter electronics, which communicate over ANT+ and Bluetooth simultaneously. You can pair to a head unit and phone app at the same time without switching protocols. The DUB spindle interface works with SRAM's full range of DUB bottom brackets—threaded BSA, T47, PF30, BB30, or PF86/92—so the crankset adapts to whatever shell your frame uses. You'll need to purchase the appropriate DUB bottom bracket separately based on your frame's specifications.

Force-level carbon construction keeps weight reasonable for the integrated electronics, and the 12-speed chainrings use SRAM's machined tooth profiles for clean shifting under load. The crankset ships in a 2x configuration with 48/35 chainrings, which provides a wide gear range suitable for road racing, gran fondos, or hilly terrain where you want both high-speed gearing and climbing options....
