We have several power meters for SRAM MTB cranksets. Please note that each power meter only fits certain cranksets.
Left Crank Arm Power Meter
SRAM MTB GXP:
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 works with SRAM 1x and 2x cranks.
SRAM MTB BB30:
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 for this version, you must 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
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
SRAM 3-bolt MTB BB30 or GXP:
power2max NGeco SRAM MTB Power Meter
The power2max NGeco SRAM MTB Power Meter is one of our go-to power meters for SRAM MTB cranks. It’s accurate, durable, measures the power from both legs, is reasonably priced and allows you to keep your current SRAM crankset. Please note, the power2max SRAM MTB uses a 104 BCD chainring configuration, so you will need a power2max compatible MTB chainring as well.
Sigeyi AXO SRAM MTB Power Meter
Sigeyi also makes a 3-bolt power meter spider for SRAM MTB cranksets. It has quicky become one of our best-selling power meters. It has some great customer feedback and is a bit more affordable than the power2max or SRM options.
Like the power2max and Sigeyi above, the SRM SRAM Power Meter is a spider-based power meter that fits SRAM MTB cranksets that use the 3-bolt interface. The SRM fits standard and Boost cranks, features +/- 1.0% accuracy, a 2-year warranty and can fit rings as small as 30T. This power meter also uses a 104 BCD chainring configuration, so you will need a compatible chainring to use with it.
XCADEY XPOWER-S GEN2 SRAM MTB Power Meter
The XCADEY is similar to the SIGEYI AXO power meter as an affordable spider-based power meter that fits SRAM MTB cranksets that use the 3-bolt interface. The XCADEY fits Boost cranks, features +/- 1.0% accuracy, a 2-year warranty and can fit rings as small as 30T. This power meter also uses a 104 BCD chainring configuration.
In order to use these spider-based power meters, 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.
Quarq SRAM XX1 Eagle DUB Power Meter
SRAM 8-bolt MTB BB30 or GXP:
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 which fit SRAM 3-bolt cranksets, the Quarq only fits the SRAM XX1 Eagle DUB 8-bolt Crankset. If you have this 8-bolt crankset on your bike, this Quarq XX1 power meter will bolt right on.
However, if you have the 3-bolt crankset (which is much 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.
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.
Pros: Moderately priced (with the exception of the SRM which is pricey), VERY reliable, measures both legs
Cons: None
Power Meter Pedals
All SRAM MTB:
MTB power meter pedals are also an option as they can easily be installed on any MTB crankset. We have the Garmin Rally XC, SRM X-Power and SRM X-Power Flat Pedals.
Pros: Easy to install, works on any bike, can move from bike to bike, don’t have to change crankset
Cons: Some versions are pricey
I have a GX Eagle AXS Transmission Groupset. What power meter can I use?
Thanks for help.
Uwe
Hi Uwe. We actually have a really descriptive SRAM GX Transmission FAQ pertaining to this exact question and it has a lot of great options for you.
Thanks,
