The Rollerbones Day of the Dead wheel is a popular choice for skaters because it rolls well on many different surfaces. This wheel is available in four different sizes with hardness ranging from 86A to 96A. This wheel is made of a softer urethane and a hard core to give the skater both grip and roll. The lip on the wheel helps give the grip on multiple tracks allowing the wheel to compress just enough to stick to the track and not slip out in turns. These wheels are made for speed skating, rink skating, and derby or jam skating. All Day of the Dead wheels are sold in 4-packs. Sold in 4 packs.
