Sram Rival Powermeter Crank Wide 172.5mm Left DUB DM Carbon

Meet the SRAM Rival E1 DUB Power Meter—sleek design, rock-solid data. The fully integrated DUB-PWR unit is cleverly concealed within the crank spindle, eliminating the need for external pods or wires—just a stylish crankset that tracks your effort on every ride. Built on SRAM’s DUB interface, it offers enhanced durability and compatibility with all SRAM Road DUB bottom brackets (excluding Ai frames), making upgrades a breeze for most modern road and gravel bikes. Utilizing proven Quarq technology, it measures left-side power to calculate total watts, features IPX7 waterproofing, and comes with a user-replaceable AAA lithium battery that lasts over 400 hours. Plus, since the system adds less than 40 g compared to a standard crank, transitioning to power training is virtually weightless.
