Axial Racing RR10 Bomber Aluminium Wheel Hex Adapter 5mm Inner 12mm Outer 17mm RR010/1217 by GPM  [RR010/1217]

Adapter summary for wheel mounting

This aluminium wheel hex adapter is an RC-scale replacement made for Axial Racing RR10 Bomber wheel arrangements, matching the specified inner 5mm axle bore and outer 12mm hex dimensions without altering hubs or wheels. It provides the interface between axle output and wheel hex while remaining a compact 17mm thick component.

Aluminium construction reduces deformation versus standard plastic hexes and supports consistent wheel alignment under load. The listed sizes are inner 5mm, outer 12mm and thickness 17mm, and the product is supplied as a 2pcs set.

To install, confirm axle and wheel hex measurements match the inner 5mm and outer 12mm, slide the adapter fully onto the axle, then tighten the wheel using your original fastening method. Inspect for axial play after fitting and adjust seating to reduce any slack between hub and wheel.

Used for tuning, the aluminium adapter firms up the wheel-to-axle joint and can minimise flex at the mounting point, helping preserve wheel offset determined by your current hub and wheel stack. Choose these adapters to replace worn plastic hexes or to tighten the mechanical link in scale off-road rigs.
