My Klein road bike came with a 53/39 crankset. I think that the best equipment change that i ever made was converting it to a 50/34 compact crank. That change gave me a couple of hill climb gears that I desperately needed at the expense of a couple of go-fast gears that i never used.
Along the same lines, I have no use for 11 tooth cassette cogs.
