I have an opportunity to start riding track this fall and am wondering whether I can get started by using my Specialized Allez frame. I understand the dropouts are different, but my question is whether this is possible? I would plan on purchasing track wheels and crank. Any thoughts or your experiences are appreciated. Once I am able to find out whether this could be a long-term proposition, I will look into setting up using a real track frame. BTW, I have been looking at the Giant and Bianchi Pista Concept as good starter frames. Thoughts?
