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.
However, there are a couple of power meters that will work and we discuss those below.
Left Crank Arm Power Meter
As long as your RED crankset is BB30 (not GXP), the Stages power meter will work with Stages Spindle A. The Stages power meter is a left arm power meter that measures left leg power.
Please also note, whenever you are installing a left side power meter crank arm, you need to confirm you have 10mm of clearance between the left crank arm and the chainstay in order for the sensor to clear. Please see 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 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
