The Hauck Roadster Duo SL is a stroller with two side-by-side non-reversible seats which you can individually recline flat. For a newborn, a soft carrycot is also available. You can thus use the stroller for siblings with an age gap as well as for twins from birth. The larger solid wheels with soft suspension can handle all kinds of terrain.
You can identify the older Roadster Duo SL versions by the all-terrain wheels with air-filled tires, that made the strollers heavier. Over the years, the textiles have changed, the hood has lost the sun visor and the wheels are now made of foam. The latest facelift was a pre-version of the newer Roadster Duo SLX, but with wheels with a thicker layer of foam.
