Enjoy the bike hunting! I did not try the Dolce but just bought a Specialized Ruby and couldn't be happier with it! My husband has 2 older model (90's) steel Specialized bikes- one is an Allez, and the other has no markings to indicate the model- and he is happy with them as well.

As for the WSD model, personally, I am very short, with a short torso and that limited my choices to the women's specific design. But if you are not so petite and have a longer torso, the other models might work for you.

If all of them fit "on paper"- try them all and see if one feels better or fits better.

How does the Secteur differ from the Allez?
