I've got a few monster bowls around here. So sick, one of them is 10 feet deep with an 18' fullpipe section. Funnest shit ever, I go to that park just to shred in it.
The only people in the world that want sponsorships more than scooter riders are starving kids in developping countries. Jesus. Just ride because it's fun. Sponsoring every remotely good rider makes the sport look really bad.
Yes. It makes a world of difference. The bearings themselves don't need the grease, but any metal-to-metal contact (the crown race to the bottom bearing, the pinch ring to the top bearing) needs grease.
