Guide wheel selection principles:
1. It is preferred to use the same size as the original guide wheel. If there is no same, you can choose a smaller one than the original guide wheel, but you cannot choose a larger one;
2. The guide wheel and the tension wheel are not distinguished, but the original guide wheel and tension wheel of some rear derailleurs are different in size. They can also be replaced with the same size, and the chain length needs to be readjusted.
