Reffering to that chart, we ride freebords at up to 50 mph (converts to more in kph). It will be up to 80% as fast as a longboard or dirtsurfer on the same hill, due to wheel size. The main difference is that you are not just straightlining, but carving, sliding, stopping or powersliding even at incredible speed. The trucks do not 'oscillate' side to side like carveboard or flowlab because you are only on one edge at a time and you have to delibrately switch between them. What kind of wobble are you getting?
