The Sfera wheels are perfect for the execution of circles.
From the acquisition of the historic Italian company Boiani, here is the Made in Roll-Line version of the famous Star wheels.
The compound of these wheels faithfully follows that used in Star wheels, guaranteeing the same performance.
The slightly grooved surface makes the Sfera extremely silent during the counter turns.
The wide profile is specifically designed for the execution of circles.
The 63mm diameter is optimal for the maximization of roll.
Available in 5 hardnesses (colors)
