Sold in pairs (two wheels)
As the product name suggests, the CB Design Insert Wheel is designed to be used with inserts that allow you a better choice to model a real car. Like other CB Design wheels, the Insert Wheel features a hubless design, are precision-machined, have perfect concentricty and very tight tolerances, are sturdy and will take hits without bending. They also have small dimples on the wheel to make it easier to locate the set screw.
When mounting or dismounting CBD Wheels on the recommended axle (Slot.it SIPA01), resistance will be noticeable. Again, this is by design - the snug fit ensures concentricity is maintained when the set screw is tightened. The result – ZERO wheel wobble or vibration which translates into better performance whether in a straight line or while cornering.
