  • No loss of power

    Our IZALCO RACE is there when you need it. Thanks to its high rigidity, no power is lost, your calf power is converted directly into forward motion.

  • The world’s fastest quick-release axle

    Quicker and simpler: Thanks to our patented FOCUS R.A.T. quick-release axle, wheel changes can be carried out in under ten seconds.

  • No cables to spoil the visual appearance

    Ideal protection and visually appealing: thanks to its integrated cable routing, it is not possible for dirt to restrict the functioning of the IZALCO RACE.
