The rear of the Supersonic is where even more options come into play. There are two mounting options.
The inner mounting holes are on the rise from the deck (see image below). The RKP truck is flipped. When the truck is flipped at this angle it is a zero degree rear option and incredibly stable for high speed pushing. It is also effective for top-end speeds in pumping, although more effort will be required.

The second rear mounting option (see image below) is the back mount.

On the back mount, the RKP truck is standard with kingpin facing backwards. The angle for the truck is -17. Mounting a 43 degree Paris would net a 26 degree truck. The board is easier to pump in the configuration but not as fast. The deck flexes back a small amount of energy, which makes is more fun and playful.
Flex options explained
Bamboo light
The Bamboo light flex is ideal for riders under 77kg. You CAN ride this up to 86kg, but you’re going to have an easier time bottoming it out. Heavier riders are going to stress this board more, so this is something to keep in mind when riding. If you’re a rider who really wants to ride a flexible board, we recommend pairing the Bamboo light with risers and our large 102mm Hoku Wheels. That will get you off of the ground further and allow more space between the bottom of the board and the ground for the board to flex.
Bamboo medium
The Bamboo medium is the standard. Equate the amount of flex on this board to be similar to the maple 7 ply version of this deck. This is the board that will work the best for the most amount of riders. Anyone between 68 and 95kg should be able to ride this board, and riders at the top of this limit should only choose this board if they want a lot of flex. Please note that the more you weigh, the more force you will put on these boards, so if you’re near its upper limit, consider how you manage dropping off of curbs, for example. Riders toward the bottom of this limit may choose this board for a more snappy flex and a little less sag. You can create more space between the board and the ground by adding risers and larger wheels like our 102mm Hoku Wheels.
Bamboo Heavy
The Bamboo heavy is stronger and stiffer than the medium flex. Riders up to about 110kg should be able to ride this deck flat with the 92mm Karma wheels and a 50 degree truck up front (rear would be 40 or 43 based on current options). Heavier riders may be able to get away with riding this deck by compensating with larger wheels and some risers to create more space between the ground and the low point on the board.
How to set up a Supersonic deck
As a complete, there are three truck options for the Supersonic. The deck has been designed specifically with Bear Trucks or Paris Trucks in mind. You can certainly use whatever setup you want. Setting up outside of our recommended setups may require risers or angled risers. This will depend on your truck choice and the angles of your baseplate. You’ll want to consider your wheel choice in correspondence with your trucks to keep your setup from getting bite.
A standard 50 degree front is your safest choice. With the 50 degree front (Paris or Bear), you cannot get bite with 86mm McFly wheels or the 90mm Boa Hatchlings. This is as long as you have a stock cupped washer in the board-side position of your bushings. Once you start bringing down that front degree, wheelbite can start coming into play for the larger wheel option. This can be easily mitigated with risers and/or bushing and washer modifications.
We recommend 50 degree front trucks for most riders using the Supersonic LDP longboard for long distance riding and pumping. This will push the pump power toward the front of the board and make pumping more effortless.
For a rear truck we recommend the Paris 43 or Bear 40. At the inner rear mounts this will give you are near zero back truck.
For riders looking to max our their top speed, dropping the front angle may be considered. This can be combined with zeroing out the rear truck angle. Ultimately, between riding a 50 front or a 43/40 front for maximum pumping speed will come down to riding style. It is worth noting that a the lower degree front does feel a little more stable when pushing absolute maximum speed. Riders just looking to leisurely cover large distances will appreciate the efficiency of the higher degree front end.
