Visco GRP40
A top class high performance compound


Producer of high quality tires with distinctive looks and a healthy dose of Swissness. That’s the concept onza® tires continues to live by in its nineth season. Such a young brand has already achieved some impressive results. Take former team rider Roger Rinderknecht, winner of the 2012 4X World Championship title, or Marine Caribou, who became Junior DH World Champion in 2015. Wins in racing, positive tests in special interest magazines and word of mouth between enthusiasts out on the trails have all contributed to the ever increasing presence of onza® tires on bikes worldwide. These tires perform with the best in terms of traction, flat protection and weight. For 2017 you will see the work done with our team riders to develop some new products for Downhill and Cross Country Marathon.



Our products are available in over 30 countries. Visit our distributers-page to find out where to get your set of ONZA gear!

    I put a lot of trust into my tires dropping into some of these big chute lines, the new GRP40 compound will never leave doubting my traction on the way down!
