Shimano CE S70R Polarized Sunglasses. Shimano creates eyewear with the same precision and attention to detail as their superb components and the S70R Polarized Sunglasses certainly exemplify high performance eyewear in every fashion. The S70R features Shimano's innovative Metal Fit Design technology which is a beta titanium plate that connects the two separate frames. Beta titanium delivers a high rigidity versus elasticity ratio which translates to more precise tension to create a perfect fit. Combined with the 3D Digital Fit Technology, adjustable nose piece and temples, plus an adjustable lens angle, and you've never had eyewear that fit so well. Additionally, the frames are constructed of Grilamid TR90 nylon to ensure they're lightweight, strong, and durable. Two sets of lenses are included, including a Polarized option that's ideal for reducing glare from pavement, water, and glass. The polarized lens ensures a clear view with excellent distance perception and is perfect for use on bright, sunny days. The other lens color is clear which is perfect for riding in rainy conditions as well as at night.
