As the name suggests, this is the kind of board you use for freeriding. Freeriding is a mixture of downhill and slides or tricks. Often the same shape of the deck is used as on the Downhill Longboard. So a drop trough is used. The special thing about this board is its versatility. The art of a good freeride longboard is to reach high speed and still be as agile and flexible as a cruiser or carve.
Here again the well proven Reverse kingpin Trucks are great for freeriding. On the subject of angles, you have the free decision.
Smaller angle ➤ more stability
In general you should tend to use too soft standard bushings (mixture of cone and cylinder).
