Agree with the above. I treat my road bike like an appliance, where as the track bike is a very specialized tool That said, I don't do much track-type training on the road bike as I find it's just too different from my track bike for doing sprint-specific stuff. If you end up being an enduro, the road bike will be much more useful to you for REAL training than mine is for me. I had a track bike with a brake on it what was great for starts and accelerations on the road, but it's on a different continent now. That is an option if you end up being more sprint focused, but for now I generally agree with Taras- for fitness and the general stuff, a road bike is essential. Once you specialize a bit, your priorities may change, but a road bike is always going to be useful.
