Mountain bike full XC and All-Mountain bikes. Examples include the Giant Trance, the Trek Fuel EX series, and the Specialized Stumpjumper FSR, among many others. With less of an emphasis on weight, trail bikes are typically built to handle rougher terrain than dedicated XC bikes while having slacker head angles (68-69°) which provide greater stability while descending. Trail bikes are designed for approximately 60-70% uphill, and 30-40% downhill riding. Enduro/all-mountain (AM) bikes bridge the gap between cross-country and freeride bikes, such as the Trek Remedy and Specialized Enduro series, typically weighing between .
