You have several power meter options depending on the version of your SRAM Rival crankset. Please see below for details.
Left Crank Arm Power Meter
SRAM Rival AXS Power Meter Crank Arm
IMPORTANT: This power meter only works with Rival AXS DUB cranksets. It will not work with older generation Rival cranks. If you are not sure which version you have, please contact us and we would be happy to help.
This Rival power meter is made specifically for Rival AXS DUB cranksets. With this power meter, you replace your left side Rival crank arm with the new power meter version. This power meter is an easy and affordable way to add power to your SRAM Rival AXS crankset.
Please note, this power meter is available in a Regular version (for most road bikes), as well as a Wide version (for bikes with larger rear tires such as gravel and CX bikes). If you are not sure which version you need, please see this article: Which version of SRAM Rival Power Meter do I need?
Pros: Affordable, easy to install, don’t have to change crankset
Cons: Measures left leg power only

Spider-Based Power Meter
power2max NGeco SRAM Road Power Meter
The power2max NGeco SRAM Road Power Meter is one of our go-to power meters for SRAM road cranksets. 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.

IMPORTANT: This power meter fits older SRAM Rival cranksets that use the direct mount interface. These cranks can be identified by 3 bolts located on the inside of the spider which are used to secure the spider or chainring to the crank arm. Please see the image below.
Please also note, this power meter is not compatible with SRAM 1X 40T chainrings (however we do sell Praxis 1X 40T chainrings that will work).
Pros: Moderately priced, VERY reliable, don’t have to change crankset, measures both legs
Cons: None
Power Meter Pedals
Power meter pedals are one of our more popular power meter types as they can be installed on any crankset and work very well. They are also easy to install and can be moved from bike to bike. We have several models to choose from including the Favero Assioma, Garmin Rally and SRM EXAKT.
Pros: Easy to install, works on any bike, can move from bike to bike, don’t have to change crankset
Cons: None
New Crankset Power Meter
If neither of the above options interest you, you can always change out your crankset for a new power equipped one. We have several road power meter cranksets to choose from. Depending on the crankset, you may be able to use your existing bottom bracket, otherwise it would need to be replaced as well.
Pros: Depends on the crankset – many great power meter cranksets to choose from
Cons: More work to install, potentially more expensive
