SRAM's Force AXS E1 DUB Power Meter Crankset takes the spider-based dual-sided power meter architecture from Red AXS and drops it into the Force tier, and it's the crankset most riders end up on when they want race-accurate power data without stepping up to the Red price tag. The Force E1 carbon crank arms were redesigned for this generation and shed 60 grams over the previous version, closing the weight gap to Red considerably. If you're building or upgrading a Force AXS drivetrain and want power baked in from the start, this is the crankset that came on the bike.

The bigger change here is the Thread Mount chainring interface. Instead of the power meter and chainrings being permanently bonded together, the chainrings now thread onto the power meter, which means you can swap between 46/33T, 48/35T, and 50/37T combinations without buying a whole new power meter every time your terrain or fitness changes. SRAM's Thread Mount Chainring Removal Tool handles the swap. The full chainring surface stays in contact with the power meter body, which SRAM credits for cleaner shifts under load and more direct power transfer.

Power measurement is accurate to within ±1.5% and unaffected by temperature or weather, and because the strain gauges live in the spider rather than the spindle, the crankset reads both legs independently and reports true left/right balance rather than doubling one side. A CR2032 coin cell keeps it running, and the AXS app handles firmware updates, calibration, and battery monitoring wirelessly.... Read More
