Full-suspension Mountain Bike
Cross-country (XC) mountain bikes are designed for endurance mountain biking with an emphasis on pedaling efficiency, climbing ability, and lightness.
The most well-rounded of mountain bike styles, falling between Cross-country and All-mountain/enduro bikes in terms of their balance of weight vs. strength and uphill vs. downhill capabilities.
Full-suspension All-mountain/Enduro bikes excel at technical, downhill runs at the cost of some climbing efficiency.
The most aggressive of mountain bikes, Downhill/Freeride bikes have long travel suspension and are designed exclusively for high-speed downhill performance.
