What is the difference between the sport model and the XC model? I understand the XC disc comes with disc brakes, but they have different forks. Which one is better? Are they for different uses? I am leaning towards the XC disc -- does it have better components? I tried doing research on the forks but I know they aren't top of the line but I am a beginner so it doesn't really matter.
