Radar Halo Wheels (4-Pack) Achieve world class edging without sacrificing grip! The shockingly lightweight Radar Halo features our innovative, signature H-shaped hub. The inner and outer edges of the hub are oversized, which reduces the amount of urethane on the edges of the wheel. This makes it easy to perform stops and offers excellent response. The middle of the hub has room for more urethane, which offers grip, increases control, and improves ride. The Halo is sold in packs of four wheels. For a full set of wheels, be sure to select a quanity of two. These 38mm x 59mm wheels are available in 10 hardnesses/colors; purple 84A, orange 86A, teal 88A, yellow 91A, pink 93A, blue 95A, green 97A, white 99A, black 101A, and gray 103A.
