Hi, I have a FSA 53/39 s-10 chainring with 110BCD, can I change the 39T inner ring for a 34T N10 110bcd chain ring?
also what is the difference with the numbering S-10 and N10?

    I think you should be able to find one that will fit but you will have a big jump going from ring to ring which might mean your front shifting is compromised. Depending on what you have on the back, the total capacity of the chain might be an issue also. I may have made the last bit up so wait for someone that has more of a clue to comment.

    Regarding the model number, Google says:

    You'll need to change the outer ring as well if you want a 34 inner ring as the jump from 34 to 53 is too big. Usually, a compact chainset has a 50 tooth outer with a 34 inner...oh, and you will have to adjust the front derailleur to get the correct gap (move it down the seat tube/ braze on mount.
