Atom Sub 7 Indoor Wheels are considered Atom's best indoor wheel for competition level inline speed skating. An improved Q-ring enhances overall speed, grip, and durability.
The Atom Matrix inline skate wheels are the next up the ladder from the Atom One wheel. The Matrix wheels are a little harder, with a newer urethane formula that provides more grip, roll and durability. Designed for road skating, but some have told us they like these on the track as well.
