If you are seaching for lower gears the most practical solution would be to swap your 8 speed cassette with a mountain cassette, 12-28, 12-30, or even 12-32. The only catch is your rear short cage derailleur most likely will not be able to handle the larger cog, thus requiring you to swap the derailleur with a long cage.
