XRAY 329901-M Rear Aerodisk 12mm Hex Wheels  [XR-329901-M]

Aerodynamic Rear Wheels for Competitive Use

The XRAY 329901-M rear aerodisk wheels are developed for precise, reliable track performance. With a 12mm internal hex they fit both 2WD and 4WD vehicles. The countersunk centre area seats the wheel nut deeper, helping stability during high speed runs.

Material Choice and Traction Balance

These wheels are made from a flexible yet durable material engineered to resist impacts and preserve shape. Their medium hardness aims to balance grip with wear resistance, making them appropriate for a variety of racing conditions. The aerodisk sides help reduce aerodynamic drag for steady speed.

Structural Ribs for Reduced Flex

Inner reinforcement ribs limit deformation under pressure, supporting consistent handling and predictable behaviour on the track, especially under heavy corner loads.

Five Pair Pack for Value

Supplied as 5 pairs (10 pieces), the pack includes an extra pair for spares or quick changes. They are a practical upgrade path for XB2 and XB4 runners seeking rear-end improvements.
