The power2max is one of our go to power meters for MTB. It’s a superb power meter in that it’s accurate, extremely durable, measures power from both legs, is reasonably priced and allows you to keep your current SRAM crankset.
This is the power2max you would need:
power2max NGeco SRAM MTB Power Meter
IMPORTANT – The SRAM XX1 Cannondale-AI DUB crankset uses an extra long spindle and 6mm offset (non-boost) chainring, so you would want to select the 1X Standard 104 BCD option on the product page.
Please also note, in order for the power meter to fit, you need to ensure you have a direct mount SRAM crankset or a modular SRAM crankset that uses the 3-bolt interface. Please see the image below.
Lastly, please note, the power2max uses a 104 BCD chainring configuration. So you will need a power2max compatible MTB chainring as well.
