SRAM Force AXS DUB Powermeter Spider Crankset
SRAM Force AXS DUB Powermeter Spider Crankset Info
The SRAM Force AXS DUB Powermeter Spider Crankset pairs SRAM's Force AXS D2 crankset with an integrated Quarq power meter built into the spider, giving you dual-sided power data without bolting on a separate unit. The power meter uses Quarq's D-Zero measurement technology, rated to within 1.5 percent accuracy and built to hold that accuracy through temperature swings rather than drifting as conditions change over a ride.
Unlike single-sided power meters that estimate total output by doubling one leg's reading, this spider measures power from both legs independently, so the number on your head unit reflects your actual left/right balance rather than an assumption. The measurement electronics live inside the DUB spindle, adding only about 40 grams to the crankset — a small tradeoff for full dual-sided data. It runs on a single CR2032 coin cell rated for roughly 200 hours of riding, swappable without tools, and connects over both ANT+ and Bluetooth so it pairs with essentially any modern cycling computer, watch, or app.
The crank itself uses SRAM's DUB bottom bracket standard and a direct-mount chainring interface, a combination built to balance stiffness, durability, and weight in one package. Chainrings use SRAM's X-SYNC tooth profile with a consistent 13-tooth gap between the two rings, which keeps shifting fast and reliable in the 2x setup this crankset is built around — a meaningful detail since inconsistent tooth spacing is a common source of hesitant front shifts on other cranksets.
At $549.99, this is a crankset for riders who want power data as a built-in part of their drivetrain rather than a separate accessory, and who are already running or planning to run SRAM AXS. It's suited to road and gravel riders training with structured power targets, since the combination of accurate dual-sided data and SRAM's electronic shifting integration gives you a complete, matched system rather than a power meter added on after the fact.
