I'm looking at a new bike to replace my older road bike. I have a good mt bike.
Living near the Arkansas Ozark Mountains, I often find myself creeping up a hill in my largest (32 teeth) rear cog. The bikes I'm looking at have 11-25 and 12-27 rear cogs.
Would it be feasible to have the bike shop change out to something like a 11-32 or even 11-34? Would this affect the performance of the shifting? Would I need to replace any other parts of the shifting mechanism? Would I be looking at much expense?

Post on mechanics board. Derailer might object, Chain might need to be longer, you might need a new chain if it does not work with your rear cassette and clicks. I assume yoiu will keep the same number of gears.
