Everyone wants the best of both worlds, but you have to prioritize the most important features. So if you're looking for the lightest neck in the world, keep looking. If you're looking for a street neck that will perform every day, your search can stop here, this one is for you.\n\nThe bottom is completely flat.\n\nThe ends of the deck can be changed when they are worn, instead of wearing down the deck itself.\n\nOur small Friend mudguard is included. You can slide it near any wheel size to maximize foot space on your deck.\n\nWe made sure that the headset bearings are well adjusted.\n\nThe type of paint used here has extremely low friction, this one slides like butter, no need for wax.
