I currently have a Giant Cypress hybrid. In the spring I hope to have the money saved up to get a road bike. I have been cruising around the different bike websites checking out thier bikes and what components they have.

my problem is i don't know enough about the components and lingo to know which one is better. Example the Specialized Dolce and the Specialized Dolce Elite. The dolce has chainring of 50x42x30t whereas, the elite has 50x39x30t. I assume the elite is better, but am not sure why. Where can I find an book or website that expalins what everything means and how to tell what is better. I went to the Shimano site so i was able to piece together the differnce between these 2 bikes some what, but gosh I am so new to this some eye opening help would be helpful.

Thanks
Shelia
