51mm
The truck has the most mass, but because it is at rest, the skateboard has the most momentum.
skateboard.....if velocity is zero,then momentum is also zero.
try taking out the bearing with your truck
The skateboard have wheel & axle and screw, the wheel is obvious the wheel and the axle is the truck and i think the screw is the hardware.
thunder, tensor, grindking, krux etc.
A moving skateboard has greater momentum than a heavy truck at rest. Momentum is determined by both the mass and velocity of an object, so even though the truck may have more mass, the skateboard's velocity contributes more to its momentum.
Alberta Canada requires 5/16 inch or 8MM above rivet head or if bonded friction material, 8mm above metal.
Thunders skateboard trucks feel like a planking balancing on a point thus making it better than the Independents skateboard trucks.
loosen your truck bases then tighten them up straight
compare it to the width of your board! the wider the board the lower and wider your trucks need to be!
tighten your trucks alot or unscrew the truck and take off the bushing and snap it or something.
