Datasheet: The slider tip magnesium Alpinestars is designed to ensure a good feeling in contact with the asphalt and, unlike that of titanium, does not create sparks in contact with the road surface. Magnesium is offering a good level of resistance and greater protection with the blocking points that are subject to wear if unprotected, thus making the boot unusable. The slider has an ergonomic design that magnesium parts are placed in a part termoiniettato PU double density. One part is elastic so as to be easily mounted on the connectors of the boot while the other is more rigid to provide a stable and secure. The part PU termoiniettato connects the slider to the boot by 'fins' interlocking ensure that the positioning and fixing of the sliders and facilitate its replacement. The magnesium frame is lightweight and aerodynamic, compatible with the boots and road racing series Supertech, Alpinestars S-MX and GPS.
