SRAM Apex AXS Power Meter Spindle Assembly

This unit uses SRAM's DUB-PWR technology to measure power directly from the left side of the spindle. It calculates your total power output by doubling the data captured from the left leg, which is a standard and reliable method for many power meters.

This spindle is designed specifically for SRAM DUB cranksets. You will need to ensure your current setup uses the DUB bottom bracket standard to install this assembly.

The battery is designed to last over 400 hours of ride time, so you won't need to charge or replace it very often. When it does eventually run low, you will need to replace the battery unit itself, which is straightforward given its integrated design.

Yes, the unit carries an IPX7 waterproof rating. This means it is fully protected against water immersion, making it safe to ride in heavy rain or through puddles without worrying about damaging the electronics.

Not at all. Because the electronics are integrated directly into the spindle inside the bottom bracket, the design is completely stealthy. It maintains the clean, minimalist look of your crankset without any external pods or sensors.
