I would not recommend these wheels as they can explode if you skate a lot of vert, if you want decent wheels buy a set of Darkstar Lightning core as they are slim and much faster and you wont slip out on them.

The Ricta Ricta-aircores are terrible....just not worth the extra money....and honestly.....can they make your board that much lighter..stick with solid wheels.

Ricta Ricta-aircores pay extra for these wheels, they are not as light as advertised and the autobahn duoduros are lighter for the size.

The Ricta Ricta-aircores wheels are Pretty cool. They only cost me $36 at my local skateshop in Raleigh. They are Really light and weigh as much as three wheels.

I dont kno about these Ricta Ricta-aircores wheels but myt friend charlie's ones just exploded from one weeks intermediate level skating (no huge stair sets/ big drops/ crazy slamming) but they could have been a bad batch.

If you got extra cash then buy em

Overall, these Ricta wheels are worth buying if you are willing to risk breaking them in a hurry or if you don't care about how much you spend on your wheels.
