There are several power meters that will work on a SRAM Force crankset:
Left Crank Arm Power Meter
Stages Cycling makes the Stages Carbon for SRAM BB30 Power Meter which is compatible with the SRAM Force 1, Force CX1 and Force 22 BB30 cranksets when used with the Stages Spindle B. (Please note, this is NOT compatible with SRAM Force DUB or GXP 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: Easy to install, don’t have to change crankset
Cons: Measures left leg power only
Spider Power Meters
SRAM RED/Force AXS 107 BCD Power Meter Spider
The SRAM RED/Force AXS 107 BCD Power Meter Spider works with SRAM RED/Force ETAP AXS cranksets that use the 8-bolt interface. Assuming you have a compatible crankset, this would be our first choice of power meter. It is reasonably priced, measures both legs and allows you to keep your current crankset.
If you don’t have an 8-bolt interface, you can still use this power meter but would need to purchase new 8-bolt cranks as well as a new bottom bracket as well.
SRAM Force AXS Power Meter Spider
Please note if you have 43/30 chainrings, the power meter will not fit. This is because your 43/30 chainrings use a 94 BCD and the SRAM RED/Force AXS 107 BCD Power Meter Spider uses a 107 BCD. So you would have to move to the next smallest chaining combination which is 46/36. On our product page, you can purchase new chainrings along with the power meter if you need them.
power2max NGeco SRAM Road Power Meter
If your SRAM crankset uses the 3-bolt interface, we would recommend the power2max. Like the Quarq above, it’s a spider-based power meter that measures both legs. power2max makes some of the most reliable power meters we sell and we use them on a number of our own bikes.
power2max NGeco SRAM Road Power Meter
Pros: Moderately priced, VERY reliable, don’t have to change crankset, measures both legs
Cons: None
Power Meter Pedals
Power meter pedals can be installed on any crankset. We have several models to choose from.
Pros: Easy to install, works on any bike, can move from bike to bike, don’t have to change crankset
Cons: None
