I am looking to invest in buying a few Shimano Ultegra small chainring spares.

Currently I have a 50/34 and I am thinking of getting a 36 or 39.

My question is can I change 34 to 36 or 39? Or do I have to stick with 34?

    No, you don't have to stick with 34

    Or you could just go to a nice tight cluster on the rear and gain tighter gearing in both rings.....

    Also depends on what Ultegra you have, if it's 6700, then no you can't change rings.
    Not without a missmash of aftermarket parts anyways.

    Of course you can change the rings. The inner ring is a standard 5-bolt fit anyway.

    If you buy a 39t make sure it is 110BCD and not 130BCD.
