What power meter will fit my SRAM GX DUB MTB crankset?

There are several power meters that will fit a SRAM GX DUB MTB crankset. Some of these will measure left side power, whereas other options will measure power from both legs. Dual-sided versions usually cost a bit more.

Left Crank Arm Power Meter

Stages Carbon for SRAM BB30 Power Meter

This Stages SRAM BB30 Power Meter fits SRAM MTB DUB cranksets when used with Stages Spindle G. The Stages is a left side power meter. This means you simply swap out your current left side crank arm with the Stages. This makes installation quick and easy, however the Stages only measures power from the left leg.

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

 

Power Meter Spiders

power2max NGeco SRAM MTB Power Meter (staff favorite)

The power2max NGeco SRAM MTB Power Meter is one of our go to power meters for SRAM MTB DUB cranksets. It’s accurate, reliable, measures the power from both legs 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 that uses the 3-bolt interface. Please note, the power2max uses a 104 BCD chainring configuration. So you will need a power2max compatible MTB chainring as well.

Sigeyi AXO SRAM MTB Power Meter (staff favorite)

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.

SRM SRAM MTB Power Meter

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 both standard and Boost configurations, features +/- 1.0% accuracy, a 2-year warranty and can fit rings as small as 32T.

This power meter uses a 104 BCD chainring configuration. So you will need a compatible chainring to use with it.

Power Meter Pedals

MTB power meter pedals are also a great option as they can easily be installed on any MTB crankset and can be moved between bikes if necessary. We carry every option available including the Favero PRO MX, LOOK X-Track, Garmin Rally XC, SRM X-Power and SRM X-Power Flat Pedals. One drawback here however is the price, especially with the dual-sided versions. MTB power meter pedals are on the expensive side compared to other options.

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
