SRAM Apex Power-Upgrade AXS WIDE Left Crank Arm
Couldn't load pickup availability
The SRAM Apex Power-Upgrade AXS WIDE power meter is a left crank arm upgrade that measures power without changing the crankset. The sensor is hidden in the DUB spindle, so it fits almost any bike and keeps the installation discreet. It measures power from the left leg and uses that to calculate total power in watts, useful data for training with reliable numbers.
The system uses proven Quarq reliability and an AAA lithium battery that lasts over 400 hours, about a season of rides, and can be replaced by the user. The unit is IPX7-rated, withstands 1 m for 30 minutes, and adds less than 40 g compared with a standard crankset. The available version is black, with a 160 mm crank arm and DUB bottom bracket, so check these details before ordering.
