Power meter compatibility FSA/Cannondale

Hi. I have a FSA Gossamer B30 and would like to know if it is compatible with this power metter: Power2Max NG eco Bicycle Power Meter Cannondale Direct Mount FSA

No, that Pm is only compatible with cannondale crank arms. It just happens to have FSA chainrings

You could replace the non-driveside crank arm with something like this Stages Cycling Store | Stages Power L - FSA SL-K BB30 | buy online

But it’s not the same price! You could get a pair of Favero Assioma Uno power meter pedals for less.
