Recognized as a mecca of mountain biking, Crested Butte is also a pioneer of fat biking. Fat bikes use oversized tires to boost stability and traction while you’re riding on packed snow or slick roads, through sand or deep gravel, or on trails with mixed conditions. Since the 1980s, Gunnison Valley local Dave Wiens — Mountain Bike Hall of Fame inductee and executive director of the International Mountain Bicycling Association — has been pedaling trails across the valley year-round.
