The Vault Mag is dead. Long live the Vault Mag! The new Vault Mag SL is here, born from our quest for production methods that are more environmentally friendly and less wasteful. Thanks to the unique use of pressure die casting technology, the Vault Mag SL achieves these goals. The combination of lightweight magnesium body and Ti Nitride axle equates to just 332g per pair. When weight and performance are paramount, the Vault Mag SL delivers. Six benefits of the magnesium casting process: 1. Most of the magnesium used is extracted from seawater. 2. Magnesium uses less energy to process the material than aluminium (bauxite). 3. Casting magnesium uses less energy to make the finished product (than CNC aluminium). 4. The casting process wastes very little material. 5. Any waste material is recycled on site (zero waste). 6. Magnesium is non-toxic and is very safe for manufacture and use.
