These wheels measure 83mm x 52mm with a soft and smooth 78A hardness.
The urethane is poured around a center set core. Center set core wheels wear down slower because the load is spread evenly across the width of the wheel. Centerset wheels can be prolonged by flipped them if they start to cone, creating a much longer life than other types of bearing seat positions.
These wheels are much larger than standard size longboard wheels. Larger wheels don't get hung up as much on cracks, pebbles, and rough pavement. They also cover more ground per rotation, so once you get moving they hold speed better.
These wheels have a wide contact patch which equates to better control at speed and more grip.
Also includes a set of Amp 7 Bearings, Spacers, and Washers. This set of Abec 7's are made with 8 hardened ball bearings for impact absorption and gas-washed surfaces to provide less friction. Amp bearings are strong Abec 7 bearings capable of high speeds and durability.
