The R-Design Flat Plate Wheelie Bar is a high quality, lightweight wheelie bar option for vehicles that use a Traxxas style mount. Using a modular design this wheelie bar can be tuned for varying track conditions. With a length of 300mm this provides stabile launches run after run. The center spine can be swapped for shorter or longer variants to adjust the amount of flex the bar has. A medium and extra small spine is included to give you tunability out of the box. Alternatively, the bar also has mounting points for a turnbuckle if you would prefer that method instead. The polyurethane rubber wheel is 30mm in diameter and 15mm wide. It features a crowned surface to achieve a more forgiving feel when the tire makes contact with the ground. The included 6x12x4mm ceramic bearings ride on machined aluminum bearing seats and are aligned using a brass spacer to ensure proper function and durability.
