well... i put almost 10,000 miles on my dolce elite (2004 model) before i upgraded it to a ruby pro! i rode numerous metric centuries, centuries, and double metric centuries on the dolce... and it was a great bike! (heck.. the first time i rode a century... i could kept going! and that was before we figured out i needed a shorter stem!)
i will say that the ruby is a much smoother ride than the dolce! but then... i guess that is to be expected from a carbon bike! i assume... that the lower end ruby's are also smoother.... even though they are each made with a different grade of carbon... different handlebars.. etc.... because of the zertz and carbon... they should be smoother than an aluminum bike!
i have to parrot what the others have said... test ride them and buy the bike that fits best!
hope she has fun with her new bike!!!!!
