The power2max NGeco SRAM MTB Power Meter 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.
In order for it to fit, you need to ensure you have a direct mount SRAM crankset or a modular SRAM crankset. These cranks can be identified by 3 bolts located on the inside of the spider which are used to secure the spider to the crank arm. Please see the image below.
Please note, the power2max uses a 104 BCD chainring configuration. So you will need a power2max compatible MTB chainring as well.
