When you have an experience like you did with the Cannondale, you have a great opportunity to see what kind of bike store with which your dealing. Give them feedback on your riding experience with the bike, and watch carefully how they respond. If they actively listen and work to help find the right fit, this is a good thing. If they ignore your comments or blow them off, you might want to consider a different shop. While fit can make all the difference in the world concerning your wanting to ride, how far and fast you can ride, and how comfortable you are, a good bike shop makes all the difference in terms of you cycling happily for years to come.
