Maybe I can just adjust the front derailleur so that it is limited to two cogs instead of three? I'll hve to try it out.
Just do this. Your kid doesn't need 30 speeds, I promise. You can do this by turning in the high limit screw on the front derailer.
Or put a less radical cassette on there. Your kid surely doesn't need a 22/36 combo either.
