You can often run that changer with a 28 but everything has to be "on spec". Some of those variables
are chainring spread and the shape/length/angle of the frame's gear tab. 28 is about the limit so
anything less than perfect about the system makes shift to 28 sticky or worse. ("Worse" would be
one-way shifting to the 28 - you can't shift back out to the 24)
