If you are attempting to change the FSA double into a triple it won't work. I believe the Shimano crankset has a 130 bcd for the larger rings and a 74 bcd for the smallest ring. The smallest ring that can have 130 bcd is a 38 tooth, if my recollection is correct. Since the FSA is a double, it will only have the 130 bcd for the two larger rings and will be missing the 74 bcd for the small ring.
