There are several power meters that will work on a FSA Gossamer BB30 crankset:
Left Crank Arm Power Meter
Stages Cycling makes the Stages FSA SL-K BB30 Power Meter which is compatible with the FSA Gossamer BB30 crankset. Please note, this is a carbon power meter crank arm, which is why it’s a bit pricey. Stages does not make an aluminum arm that will fit. Please also note, for a time around 2014, FSA used a pinch bolt style interface (Shimano). You need to confirm that your crankset is not that type, because Stages doesn’t have an arm that will work.
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
Power Meter Pedals
Power meter pedals can be installed on any crankset. This is a very popular power meter type as they fit any bike, are easy to install and can be moved from bike to bike if necessary. We carry power meter pedals from Favero, Garmin, SRM/LOOK and Wahoo. This includes pedals for SPD-SL, LOOK Keo as well as Speedplay cleats.
Pros: Easy to install, works on any bike, can move from bike to bike, don’t have to change crankset
Crankset Power Meter
Of course, you can also choose to replace your crankset entirely for a new one. This is usually a more expensive option, but opens up the door to many possibilities. Here are our Crankset Road power meters. Assuming you don’t want to change your bottom bracket, you will want to look for a crankset that has a 30 mm spindle. This includes:
- InfoCrank M30 Power Meter
- ROTOR 2INpower Power Meter
- ROTOR INpower Power Meter
- power2max ROTOR ALDHU Road Power Meter Crankset
- power2max Easton Road Power Meter Crankset
- SRM Origin Road Carbon Power Meter
- ROTOR INspider ALDHU Road Power Meter Crankset
Pros: Accurate, reliable, measures both legs, some great power meters in this list
Cons: More expensive, more work to install
