are FSA cranks / rings a slightly different size to Shimano?
I just went to replace my 36t SFA ring with a Shimano 32 one and while the BCD is exactly the same (104) the shoulder or tabs or whatever you call them on the spider arms are about 1 or 2 mm bigger so it wont fit.
Do I need to buy an FSA ring? as I cant be arsed to file all the steel edges off the Shimano one.
