Fox Speedframe Pro cycling helmet Based on the knowledge of professional MTB riders, a new Fox helmet Speedframe Pro was created. It is equipped with the latest technologies, which are dominated by the MIPS impact protection system (absorbs and transmits energy on impact so that the head is protected as much as possible) or the Varizorb EPS antimicrobial inner liner. The shield / visor on the front is adjustable. There is also a helmet size adjustment 360° Fit system that adapts to the head. The Fidlock SNAP buckle allows quick and easy tightening of the helmet, even with gloves on. The helmet is compatible with cycling goggles.
