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, 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: 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.
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
