The Trampa Dampas are a great invention from Trampa and take the egg concept to a new level. They are designed slightly longer than an eggshock to fill the whole gap in between the cups in a matrix truck so there is no wobble in the top of the truck and screwing the springs down is not required. The 3 balls design also helps to give progressive compression and damping to the truck.
There are 7 different grades of stiffness:
Softest - Orange 55
Very Soft - Pink 60
Soft - Yellow 65
Medium - Green 75
Firm - Red 80
Very Firm - Blue 85
Firmest - White 90
Most riders would be happy with the Soft (yellow) or Medium (green) dampas as they are still stiffer than most other brands. The Extra Stiff are more useful for big freestyle riders dropping demo ramps etc where there is very quick acceleration and not much requirements for turning! The very soft are for street carving and not high speeds.
