The ergonomic, lightweight design allows air movement and cooling. The CPC polymers vary in density and use the athletes kinetic energy to actively manipulate the skin surface to stimulate nerves and improve blood circulation, preventing numbness.TiroX RailRail light-alloy steel, this material is highly resistant to traction, and torsion for its light weight it’s for these reasons it is used in used in the aviation and aerospace industry. TiroX then turns out to be a rail with a good balance between weight and strength, that doesn’t fear the normal stress that addresses a bicycle.Connect Power ControlPrologo’s patented name for these new saddles featuring dense bunches of short, suction cup like gel polymer tubes. This technology has been used in Moto GP and Formula 1, largely in gloves for the racers, but Prologo are the only ones to use it in cycling.Semi-Round profile for medium to long ridesCPC TechnologyRails: TiroXSize: 280mm x 135mmCover: MicrofibreRail Material: AlloyRoad: Yes
