SRAM Apex AXS Crankarm Power Meter

Spindle-based power meters, like this one, measure power directly at the drivetrain, which often results in a more protected and stable reading compared to pedal-based systems. Because the sensor is housed inside the bottom bracket area, it is shielded from impacts and external elements, offering a cleaner, more integrated look.

This power meter is designed specifically for use with SRAM DUB bottom brackets. Before purchasing, verify that your bike frame is compatible with the DUB standard to ensure a proper fit.

It is very straightforward. The system uses a standard AAA lithium battery that you can replace yourself without needing any specialized tools or a trip to the bike shop.

Yes, it features an IPX7 waterproof rating, meaning it is built to withstand heavy rain, mud, and road spray. You can ride with confidence in demanding conditions without worrying about the internal electronics.

Not at all. The system is designed to be lightweight, adding less than 40 grams to your total bike weight, which is negligible for most riders.

You will get over 400 hours of ride time from a single AAA lithium battery. For most cyclists, this means you will only need to replace the battery once or twice a year depending on your riding frequency.
