Fox’s open-face Speedframe helmet range has just received a massive overhaul, and its focus on protection has secured a coveted 5-star safety rating from helmet test lab, Virgina Tech. The range-topping Speedframe RS going even better and coming out top in an evaluation of 250 trail helmets, while the cheaper Speedframe Pro took second place. This moves things on from the previous Fox Speedframe that we rated highly when we tested it, and puts it firmly in the running for a spot alongside the best mountain bike helmets right now.
