Do you need wax to grind on aggressive skates?

Answer 1

Not Really The Bottoms Of Scooters Are pretty Slick When It Comes To Grinding Flat Bars

But i do think grinding on a curb is harder to grind without wax on your scooter, so i think you do need a little waxing to the bottom of your scooter (because a curb isn't as slick as flat bar)

Answer 2

No, you just need enough speed to get you all the way down the rail.

Answer 3

Depends on the rail and speed your going. Some wax is nice but not always needed.
