I'm curious as to why you're getting a new bike, too, if the Dolce is so comfy.
In any event, don't feel bad about buying a bike at one store and then servicing it at your favorite LBS. I'm sure they'll be happy for the business, especially since a lot of shops make their money in the service department anyway.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
