I'm looking to swap out some 175 FSA SLK cranks I have for 172.5 FSA cranks that I found a good deal on. My 175 is 46/36 and the 172.5 cranks have 52/38. Both have a BCD of 110 so are the two chainrings interchangeable? I'm looking to keep the 38 on the 172.5 cranks, but swap over the 46 from the 175 cranks to the 172.5 cranks so in the end I'd have 46/38. I feel like swapping over shouldn't be an issue, but I'm not 100% so I figured I'd ask.
