    How big of a chain ring has the person put on the chainset? 52? 53? 54? 55? 56? The chain rings can be changed.

    They should have the same bolt circle (?) diameter (BCD) 130mm so they should be interchangable.

    As Tunney says though they may have different No. of teeth. This will affect your gear ratios but not the functioning of the drivetrain.
