Inspired by Speedcraft's legendary success on cycling's biggest stages, S2® is 100% speed that has been newly refined for everyday sports performance. Our innovative technologies and signature lens have been tuned for riding at any level. S2®'s laser-etched edging provides the look of a full frame in a rimless cylindrical shield, for 360-degree visibility and comfort.
Photochromic lenses automatically adjust their tint to match changing light conditions. Using a reactive pigment that senses UV intensity, this technology shifts from a Category 0 to a Category 3 tint in under fifteen seconds.
