The benefits of the standard Aerotwin blade are: Evodium flex rails Balanced force distribution and optimal aerodynamics to clear every portion of the swept range with unexcelled efficiency Minimum wiper-induced wind noise thanks to the reduction in aerodynamically exposed surface area Improved winter performance – no ice formations on joints and metal frames Innovative plug-on connection for ultimate ease in blade replacement Elegant styling replaces joints and frames Integral aerodynamic spoiler Even distribution of applied force inhibits uneven wear
