The Sector 9 Race Formula 71mm longboard wheels deliver all the downhill thrills without the frills. The 61mm contact patch provides great grip for cornering, while the offset, fiberglass infused Cosmic Core enhances slide control and increases roll speed.

Downhill - To go fast and stay in control, you want a big wheel with a lot of contact with the pavement.
Carving/Cruising - Carving/cruising wheels meet the needs of many different skate disciplines but generally, have a good roll speed and are soft enough to handle craggy streets riddled with cracks and rocks.
Offset - The most popular; offset cores offer a more forgiving slide initiation and hookup, while still providing ample grip and control in your slide.
Square Lip - The most grip allowing you to carve deeper and take tight lines around corners without worrying about losing traction.
Smooth - The natural shiny finish provides extra grip for railing corners and is more responsive when pumping/carving compared to wheels with a stone ground finish.
Race Formula - This is Sector 9's fastest and most evenly wearing urethane compound.
Cosmic Core - The Cosmic core increases roll speed and provides better control through slides.

Even when accidentally running over the “rumble strips” or an occasional reflective marker on the center line, I had no issue with these wheels.
