Endura Spectrum, Cycling SunglassesTHERE ARE SEVEN kinds of Spectrum shades available from Endura but the most versatile is this blue lens version. They give a crisp increase in contrast for better depth perception in low light or hazy conditions, and yet they aren’t too bright when it’s sunny. You could also buy a clear or yellow pair for grim days, the blue for all-round use, and the Smoke lens for sunny days and still only spend £50.The arms can be bent into place for adjustment. For the money these are fantastic value performers.
