Does anyone know if there are any differences whatsoever between the 39 and 53t chainrings on cranks set up to run triple chainrings and the ones that come on doubles? I am taking off the 30t(going double) and was curious if the other two chainrings need to be replaced also. Thanks!

The triple 39 middle has shift ramps. Not an issue if used with a double.
