DS Series is the ultimate hybrid: part refined city bike, part adventurous trail ride. Fast 700c wheels, capable suspension, and a light, strong frame make DS the go-anywhere choice.

Available in up to four sizes for a tailored fit, Quantum features great ventilation, excellent coverage, and of course Bontrager's signature out-of-the-box comfort and incredible ease-of-use. A removable visor adds to the value of a helmet that feels just as at home on the trail as it does on the road.
