Full-frame eyewear trades a gram or two of weight for meaningful gains in protection, and if you ride aggressively on trails or gravel where debris kicks up unpredictably, that tradeoff makes sense. The Technium from Shimano wraps the entire lens perimeter in a goggle-style frame that keeps the optics locked in position while blocking wind, dust, and the occasional rock chip from slipping in around the edges. The dropped temple arms clear most helmet retention systems without interference, so the aggressive coverage doesn't create fit problems with contemporary head protection.

Shimano constructs the frame from Rilsan Clear G850 Rnew polyamide, a bio-based material that's 45% renewable and offers the flexibility and chemical resistance that cycling demands. The polyamide lens material is 12% lighter than equivalent polycarbonate while delivering a higher Abbe value and lower refractive index, which translates to enhanced clarity and reduced optical distortion across the wide single-lens design. The RIDESCAPE Road lens tunes contrast for pavement surfaces, helping you spot potholes, glass, and road imperfections before they become problems.

Ventilation comes from strategically placed lens slits at the upper and lower corners that promote airflow without compromising coverage. The hydrophobic coating sheds water and sweat before droplets blur your vision, while anti-scratch treatment protects the lens surface from the inevitable contact with jersey pockets and bags. When conditions change or you want terrain-specific tuning, the interchangeable lens system accepts RIDESCAPE Off-Road and Gravel options, and Shimano includes a clear spare lens for low-light riding....
