100% polyurethane for longboard / cruiser skateboards.
70 x 48 mm. One wheel weighs 175 g (700 g for all 4).
Small tip: if you want to mount these wheels on a board with low trucks (street trucks), remember to put pads under your trucks. This avoids wheelbite (when the wheels touch the deck and you get thrown off your board).
Sold in packs of 4 WITHOUT bearings.
