My three road bikes all have different gearing although two are very close. The Fuji has a 52/36 up front with a 11-28 cassette in the rear. My Specialized came stock with a 52/36 and an 11-30. After two years I replaced the rear cassette and put on an 11-32. This is an even better set up on hills. My LeMond is a triple with 52/42/30. The original cassette was a 12-25 9spd. Now it has a 12-28. If I ever were to use the 30-28 (as low as it goes) I'm probably on some hill I shouldn't be on in the first place!
