ROCKBROS SP258 ROAD TO SKY Photochromic Cycling Glasses - White

With a featherlight 29-gram TR90 frame and photochromic lens that shifts from clear to grey in seconds, the ROCKBROS SP258 ROAD TO SKY glasses keep your vision sharp from dawn patrols to high-noon sprints. UV400 protection blocks 99–100% of UVA/UVB rays, while high-definition optics deliver distortion-free clarity across the entire 18%–80% light transmittance range.

Overview

Engineered for cyclists, runners, and outdoor athletes, the SP258 adapts instantly to changing light. The photochromic polycarbonate lens darkens under direct sunlight and clears in shade or overcast conditions, eliminating the need to swap lenses mid-ride. A flexible TR90 frame withstands daily abuse, and adjustable nose pads plus anti-slip temple tips keep the glasses locked in place during sprints, climbs, or rough gravel sections.
