The SRAM Force D2 AXS 1x Power Meter Crankset combines a lightweight carbon fiber crankarm and a stiff aluminum direct mount chainring to provide us with the ultimate road performance. Inside the DUB spindle is Quarq power measurement technology, a reliable and highly accurate data collector which measures wattage on the left side. The longer DUB crank spindle also accommodates road and MTB bottom bracket standards, offering superior cross-compatibility with different brands.
