not sure why I responded when you could have Googled it, but I guess I'm here to serve your threads.

Cross Country (XC) - Mountain bikes that fall into this discipline are designed around two main factors; weight and pedaling efficiency. Many of these bikes are designed with relatively small amounts of suspension (front and rear) and have steep head and seat tube angles to allow a more forward leaning body position during riding. They are typically fabricated from Aluminum, Carbon-fiber and/or bi-metal mixtures to achieve the lightest possible frame but maintain strength for its design purpose. Cross country bikes typically have 3 selectable front sprockets along with a 9 speed (cog) rear cassette allowing for a huge variation of pedal torque vs. gear inch travel.
All-Mountain (AM): Mountain bikes that fall into this discipline are a cross between XC bikes and FR bikes. They are designed for efficient pedaling but have slightly heavier frames to handle more aggressive technical riding that may involve jumps. AM bikes tend to have greater suspension then XC bikes and many include multiple positions for different rear shock lengths. AM frames are heavier due to thicker gauge tubing and/or frame gusseting. Typically these frames are designed to have 3 selectable front sprockets along with a 9 speed (cog) rear cassette allowing for a huge variation of pedal torque vs. gear inch travel.
