The Stealth Magnesium hubs are still in the prototype and testing stages. We expect that these hubs will be available later this summer. We plan to have both Junior and Expert hubs available in Magnesium. These hubs are a few ounces lighter than the standard Junior and Expert hubs, due to the Magnesium hubshells and axles. We also have some lighter internal parts to bring the weight down even further. Like anything exotic and light, the Mag hubs will cost significantly more than the standard Junior and expert hubs.
