Axial Racing RR10 Bomber 21mm Aluminium Wheel Hex Adapters by GPM RR010/215  [RR010/215]

Wheel hex adaptors for RR10 Bomber

This pair of aluminium wheel hex adapters is an RC-scale accessory designed to widen wheel stance on the Axial Racing RR10 Bomber. Each adapter set provides a total offset to achieve a 21mm overall width increase so the wheels sit farther apart for improved lateral stability on technical crawling courses.

The adapters accept wheels with a 5mm center hole and are intended for use with 4mm threaded wheel shafts where sizes match. Mechanical retention uses a combination of o-ring, spring steel ring, springs with washers, and stainless steel screws, together with a Delrin collar inserted to hold the hex in position and reduce unwanted rotation of wheel assemblies under load.

Installation is straightforward for hobby-grade setups: slide the adapter onto the wheel shaft, seat the Delrin collar, fit the spring and washers, secure with the supplied stainless screws and pins, and verify wheel runout before the first run. These adapters are primarily for tuning track width and wheel clearance rather than altering drivetrain components.
