Veteran mountain biker Geoff Jones doesn't let winter stop him. In fact, he prefers riding in winter. "My body just seems to work better...with layering you can always unzip something and cool off...that's hard in the summer." In addition to proper layering, Jones suggests that riders wear a head band over the ears or neck gaiters on especially cold days to hold in the heat. A balaclava under the helmet is also a good idea. He also recommends neoprene boot covers on windy days. He cautions that in near-zero temperatures, cycling speeds alone can generate enough wind chill to freeze exposed shin. Jones also suggests that riders make sure they have reflective material on their clothes or bike: "In winter we tend to run out of light, so its a good idea to use reflective strips or a flashing tail light." Studded snow tires or chains can be good options in icy conditions. He suggests that riders might want to carry a piece of sandpaper to remove any ice that forms on rims and impedes the brakes.
