Cross country, all-mountain, downhill, enduro, dirt jump, huckstyle, slopestyle, slalom, four-cross, trials, urban assault, freeride, froride - it seems like riding a knobby-tired bike has a million different names. Bottom line, this is all "mountain biking." And for the mountain biker, Bell presents the new Variant helmet for the rider that does a bit of everything, but mostly just has fun.
