If we take the Paris Trucks, 50º front baseplate angle and a 43º in the rear.

So if we subtract 17º from the 43º rear truck we end up with a tail of 26º.

At the front end, is we add 15º to the 50º base plate, this gives us an effective nose angle of 65º.

This is a great set up for medium speed pumping and it allows for a lot of torque. Enough for some riders to be able to pump up some mellow inclines.

We have 40º Bear trucks at the rear and 50º in the front, but you could set it up with 40º in both front and rear - As seen in the above photo.

If you have a 40º in the front, adding the 15º would make it a 55º nose. At the rear, putting it on the 40º mount backwards, gives a 0º rear.

On this setup, there would be no added steering from the rear, but the setup is really stable. It makes for a really fast pumping setup with low torque and high horsepower. It is well suited for racing at high speeds but it does require the rider push the board to get it up to speed.

One warning. Do not use the 50º truck on the 40º rear without de-wedging it as it will give you -10º base angle and your turning radius will be greatly reduced. Subtle -1 to -3º angles may help prevent slipping out, or even further dial in top speeds for advanced riders.

Due to the non-conventional nose and tail deck angles of the Pantheon Supersonic, most stock bushings on cast trucks will be too soft for a rear truck, and too hard for your front so you will need to pair your bushings hardness for your board.

When incorrectly matched, the front truck will lift off the ground while the rear truck will still be planted. This can make the board unstable and hard to control.

When balancing on the edge of your longboard deck, you want both your rear and front wheels to lift at the same time, or the rear a few MM before the front. Bushing choice is unfortunately trial and error, until you find your sweet spot, but once you find it, your board will come to life!

This cannot be ignored. The front bushings may be too stiff to articulate and will lift on the outside front wheel, while the rear stays on the ground - or, the rear may be way too soft which will cause the board to roll in the rear more, which will worsen the lifting of your front outside wheel.

Pantheon recommends bushings that are slightly wider than standard barrel bushings - both the Riptide Cannon bushings and the Seismic Defcon barrels are a full 1” wide and they work best with the Paris or Bear trucks. This will fill the entire bushing seat and allows for the truck to turn around the bushing without extra slop.

The hangar of the longboard truck stays centred and results in a more consistent turn, better wheel bite resistance and an overall better feeling truck.

You can also experiment with different bushing shapes, but barrels give the most consistent increase in resistance through pumping your turns. We recommend starting with barrels, but if you are the more experimental type, try other styles over time. We recommend changing only one variable at a time so you can identify exactly what effect that has had on your set up.

Next, you want to take into account the baseplate angles of your longboard trucks. The higher the angle, the less leverage will be applied to your bushing, so you will need to choose softer bushings for your front trucks. 

The lower the baseplate angle, the harder your bushings need to be for that truck, as the kingpin is more vertical and your leaning force is more directly transferred into the bushings. 

Typically speaking, Pantheon recommend about a 10a split between the front and the rear bushings. If you're running your rear truck on the furthest mounted option, a typical setup for a 170lb rider might be something like a 80a - 81a front and a 90a - 93a rear.

Its not uncommon to see a 170lb rider riding with 95a, even 97a bushings on a 0 degree truck while the same size rider may have a 77a bushing on a 60 degree front, or even a softer bushing if they are running a high front end closer to 65 degree.

Bearing Rebound - For LDP longboarding, this is the most important characteristic of any given formula. If you press a bushing, a higher rebound one will return to its natural shape faster. Essentially, it's more bouncy.

A lower rebound bushing won't bounce back as much but can make for holding a nice deep turn.

For a pumping longboard setup, almost all riders prefer a high rebound urethane because they will be turning back and forth constantly.

One of the highest rebound bushings on the market are the Seismic Defcon Bushings which also offer a full 1” diameter . Other great high rebound bushings are the Riptide Barrels and the Orangatang Nipple bushings.
