Most road bike are used for speed and that requires gearing for that versus climbing. Just need a different rear cassette and possibly a new rear derailleur if you exceed max tooth size on the RD. I just moved from a long cage rear that came standard with a 11-32 in the rear an dont live in an area with mountains or hills for that matter and can get by with 25 or 28 max tooth on the back if I go some place hilly.

you should learn to embrace change, and mock it's failings every step of the way.
