SRAM RED 22 cranksets, pictured below, have a one-piece driveside crankarm and spider. This means some of the popular spider-based power meters made by companies like SRAM, Quarq and power2max won’t fit as it’s not physically possible to install a spider-based power meter on a crankset like this. However, there are a couple of power meters that will work and we discuss those below.
Stages Left Crank Arm Power Meter
Stages Cycling makes left side crank arm power meters. These power meters measure left leg power and double the value to approximate your total power.
If your RED crankset is BB30, the Stages SRAM BB30 power meter will work. Please make sure you order it with the Stages Spindle A which is required to generate the correct offset.
If your RED crankset is GXP, you would want the Stages SRAM GXP power meter. This power meter is very similar to the one above, but uses a GXP interface. Please note, with this version, there is no need to change your spindle.
Please also 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. 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 Pedals
Power meter pedals can be installed on any crankset. We have several models to choose from including the Favero Assioma, Garmin Rally, Wahoo Powrlink and SRM EXAKT.
Pros: Easy to install, works on any bike, can move from bike to bike, don’t have to change crankset
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
