The C.B. Design Insert Wheel has many of the same great features as other C.B. Design Wheels; however, it has been designed to accept wheel inserts. Machined wheels are generally available in a relatively small number of designs - one reason is many wheel designs do not lend themselves to accurate reproduction when machined (or the machining required is prohibitively expensive). For these wheels designs, inserts may be available or can be created easily using old plastic wheels. C.B. Design Insert Wheels offer the following features and benefits:
Precision machined using state-of-the-art CNC machine tools which ensure C.B. Design Insert Wheels are perfectly round and the axle bore is concentric with both the outer wheel surface and longitudinal axis of the axle.
Perfect concentricity between the axle bore and longitudinal axis of the axle is achieved by designing all C.B. Design Wheels for a specific axle (Slot.it SIPA01). Tolerances between the axle bore and axle are very snug. When mounting or dismounting C.B. Design Insert Wheels on the recommended axle, resistance will usually 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.
Accepts wheel inserts. C.B. Design Insert Wheels will accept Slot.It inserts or you can create your own inserts by turning down old plastic wheels.
Sturdy, race proven design. Some of our competitors wheel's achieve lighter weight at the expense of the durability. Ultra-lightweight wheels can be prone to "bending" - particularly when subjected to "offs" and hits during actual racing. Once bent, the wheel "wobbles" which in turn adversely affects the car's performance. In contrast, C.B. Design Insert Wheels are designed to be raced under the most demanding conditions - rest assured they will survive crashes and trips to the floor!
True hubless design provides exceptional flexibility when adjusting the front and rear track width. This is particularly important when rules specify the wheel/tire must be completely inside the fender and/or a maximum track width.
Easy to locate the retaining set screw using a small dimple machined on the outside of wheel. This is especially helpful if the tire is glued to the wheel and you can’t easily peel the tire back to locate the set screw.
