There are several power meters that will work on a SRAM MTB crankset:
Left Crank Arm Power Meter
Stages Carbon GXP for SRAM MTB Power Meter
If your SRAM crankset uses the GXP standard, you can install the Stages GXP for SRAM Power Meter. This power meter replaces your left side crank arm and measures left leg power. It is made to work SRAM 1x and 2x GXP mountain cranks.

Stages Carbon for SRAM BB30 Power Meter
If your SRAM crankset is BB30 or DUB, you can install the Stages SRAM BB30 Power Meter. Please note you must also purchase a Stages spindle along with the power meter:
Spindle C: SRAM MTB BB30 with 9 mm drive side spacer
Spindle D: SRAM MTB BB30 with 15.5 mm drive side spacer
Spindle G: SRAM MTB DUB cranksets

Stages Carbon for SRAM BB30 Power Meter
Please note, these power meters attach a sensor to the inside of the left crank arm. On some bikes, there is not enough room between the left crank arm and the chainstay for the sensor to clear the frame. Therefore, you should make sure you have at least 10 mm of clearance for Stages power meters. Also, please make sure that you don’t have a bottom bracket mounted rear brake (used on some aero and TT bikes). Please refer to the image below.
Pros: Affordable, easy to install, don’t have to change crankset
Cons: Measures left leg power only
Spider Power Meters
power2max NGeco SRAM MTB Power Meter
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 the power from both legs, is reasonably priced and allows you to keep your current SRAM crankset.

power2max NGeco SRAM MTB Power Meter
In order for it 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.
Please note, the power2max uses a 104 BCD chainring configuration. So you will need a power2max compatible MTB chainring as well.
Like the power2max above, the SRM SRAM Power Meter is a spider-based power meter that fits SRAM MTB cranksets that use the 3-bolt interface (pictured above). The SRM is available in both standard and Boost configurations, features +/- 1.0% accuracy, a 3-year warranty and can fit rings as small as 30T.
This power meter uses a 104 BCD chainring configuration. So you will need a compatible chainring to use with it.

SRM SRAM XX1 MTB Power Meter
Quarq SRAM XX1 Eagle DUB Power Meter
The Quarq SRAM XX1 Eagle DUB Power Meter is also a spider-based power meter like the power2max and SRM mentioned above. However, unlike the two previous power meters listed which fit SRAM XX1 3-bolt cranksets, the Quarq only fits SRAM XX1 Eagle DUB 8-bolt cranksets. If you do have the 8-bolt crankset on your bike, this power meter will bolt right on. If you have the 3-bolt crankset (which is more likely as most bikes come with the 3-bolt version), in addition to buying the Quarq XX1 Power Meter, you would also need to buy the new 8-bolt cranks to fit the power meter (you will see an option on our product page to add the 8-bolt cranks to your order). In addition, since the 8-bolt cranks use the DUB interface, you would need to install a SRAM DUB MTB bottom bracket on your bike if you don’t already have one.
This is also a great power meter. It’s accurate, durable, measures the power from both legs, is reasonably priced.
Please note, the Quarq SRAM XX1 uses a 104 BCD chainring configuration. So you will need a SRAM X-SYNC 2 12-Speed Chainring as well. These can be purchased on the same product page as your power meter.

Quarq SRAM XX1 Eagle DUB Power Meter
Pros: Moderately priced (with the exception of the SRM which is pricey), VERY reliable, measures both legs
Cons: None
Power Meter Pedals
MTB power meter pedals can be installed on any MTB crankset. We have both the Garmin Rally XC and the SRM X-Power.
Pros: Easy to install, works on any bike, can move from bike to bike, don’t have to change crankset
Cons: None
