actually it took me 4 mathematical equations and a total of 14000 nequalities torelize the precise physics and rocket science needed to do this. in fact up to 4 inches o fyou headtube will be cover giving a vector of up to 600 pounds of pressure to snap that which will ultimatly give the headtube a life span of about 6.4342 months and in the inequality that i have mathematically completed i found the square root of the sin of the right triangle created by the deck to the ground can simulate the pressure able to be absorbed into the headtube in deck. HOwever based on careful calculations the Lucky "EVO" deck contains over 500 dense particles each able to contain 2 pounds of pressure leading to about 1000 pounds of pressure absorbing power in vector format being able to last longer
