This is also the time when we start looking at new bike gear, and no piece of equipment is more important than a bike helmet. When worn properly, the best bike helmets can reduce serious head injuries by 60 percent. Not just in that I wear one every time I throw my leg over a bike, but I also love variety. I love matching different helmets with different kits and outfits (after all, style goes a long way on the bike), and as a road cyclist, mountain biker, and everyday around-the-town rider, I usually have anywhere from five to 10 helmets at home.
