Medium - Your classic wheel shape, versatile all-around wheel for street/park skating.
Smooth - Smooth wheels come with a shiny coating on the riding surface that feels grippy at first, but wears away quickly.
NRG Urethane - According to Ricta, NRG formula is the fastest urethane in skateboarding, it's been proven in the laboratory and backed up with testimonials from professional skaters Brandon Westgate, Caswell Berry, Cairo Foster, Tom Asta and Nyjah Huston.
99a - Offers more grip than harder wheels and more slide than softer wheels. Great for slick surfaces when you want more control.

Ricta Sparx Skateboard Wheels - framework black (99a)
The wheels are rated at a 99 duro but I'm not sure if I got sent the wrong, mislabeled size or what. I'm only 160 pounds and I got flat spots the very first session. I wasn't even power sliding or anything ridiculous, just a simple 180 was enough to do it. I tried skating around the rest of the day to see if they evened out but they never did. They look good but unfortunately mine held up terribly

They were wheels at one point, so I star I guess. Flat spot 3rd day. Nothing heavy just skirted a bs on a hip.

Ricta Sparx Skateboard Wheels
I never flatspot my wheels, but I got major flatspots on these on the first session from just sliding a switch bs 180. I keep getting flatspots even on smooth skatepark concrete. Get something like formula 4 instead, this won't save you money in the long run.
