As the only person selling the NEW Tecnomagnesio Wheels in the US, I feel there are a few facts that need to be cleared up. Yes, the Tecnomagnesio Wheels are now a hybrid Aluminum/Magnesium mix. This was done to increase the strength of the new wheels and to get the wheels DOT and TUV approved. The new Tecnomagnesio wheels are the only wheels approved for use in the US on the street as the old wheels were for racing only. The weight of the new wheel is 12.2 pounds. The repop and original wheels were 9 pounds, but you have to use a tube with them so the weight is about a wash. The new Tecnomagnesio Wheels ARE NOT repro's. They are a authorized by Tecnomagnesio, made in the original foundry with the original drawings. The wheels are powder coated the correct German racing silver and are supplied with lug nuts. If anyone has any questions or would like any more information, please feel free to contact me.
