First, I have a Bianchi Eros and Volpe.
Have been fine for me so far. I did wonder about improvements to the Volpe since I will use it for MS150 rides and the like. Nothing more. I realize it is not an expensive bike and that improvements may not be worthwhile as most have told me its a good work bike for my needs.

But when reading posts here on the Trek 520 there is mention of changing the crankset because its 30/42/52. My Volpe is the same. I read that the 22/32/44 would give lower gears.

Being new I searched here to get a better understanding of this difference, of what it would give someone and again of whether its worth my considering it for my Volpe?

Maybe its best that I wait a season or two and think of a better tour bike and improve on it.

I also was hoping someone might know of a good book or source for a newbie so he isnt posting questions here everytime he doesnt understand something and can't find it in a search. I don't want to be a pain in the butt.

Thank you for any help and direction.
