Ok so i am going to get into racing (doing a build in the coming weeks, wanted a new bike).

So I am trying to figure out what kind of Crankset to get, have been planning on getting a double or compact (my understanding is there is a difference). I like to have a big gear for descents and the such but will need something to work well in the hills here in Southern NH and around NE (since most of my races will be here).

So I guess I am looking for input on what the best gearing ratio would be.

Any input is appreciated!
