The Circles line have some of the cooler colors we could dream up. In fact we think they kinda look like Easter eggs or Dreamsicle popsicles. The Circles perform much better than most wheels out there because they are made in the USA and they definitely have unique colors. Our 101A urethane has a smooth grippy feel and is resistant to flat spots. Our 53mm Circles are pastel green. Circles are available in 51, 52, and 53 mm with our 101A Durometer urethane. Currently these are the favorite wheels of our team riders. Like all our wheels, Circles are made in the USA from the finest urethane.
