Is it true that the old double sided steel swing arm with a steel wheel is used in the rear? If it’s true, that would be truly disappointing. That means you would have to disassemble the rear suspension to fix a flat. Even the $ 25,000 Vanderhall has a single sided aluminium swing arm and bespoke aluminium wheel and disc brake. Does anyone know what the final production rear suspension will be on the “all aluminium “Super 3 ?
