Do the Cattrax still use those aluminum hubs? I went to their website and that's what it said there. So I'm thinking all those rusty and corroded car rims you see on the streets in winter, you know they are done after so many years. Eurotrax are using plastic hubs which can never corrode in a thousand years. So the question basically is: Are you willing to pay more for your EuroTrax or do you risk having to buy a cattrax every two or three years. And of course there are always exceptions meaning some cattrax will last a lifetime others a month. All I can say is that you don't see Cattrax in europe anymore as the Eurotrax have proven their worth and durability. And bad hubs are the reason for getting flat tires too. The valves will not give up as fast in saltwater as metall hubs.
