Purpose-built aluminium replacement rim offering a stiffer alternative to injection-moulded plastic wheels, optimised for consistent hub fit and repeatable wheel position during testing. The design supports dual-side mounting and stable tyre alignment for setup work.
Supplied as a single pair, the rim interfaces with Savage 21 hub geometries that accept Savage 25 dual rim dimensions. No accessory fasteners are normally included, so verify your existing hex adapters and wheel nut threads before fitting.
Setup impact: the aluminium construction increases unsprung mass relative to plastic rims and modifies tyre sidewall response; use these rims where controlled, repeatable wheel location is required for suspension and tyre development.
Intended for Savage 21 hubs accepting Savage 25 style dual rims; confirm hub hex diameter and wheel nut thread match the rim centre bore for secure mounting.
For tuning and testing, these aluminium rims provide repeatable wheel positioning and improved mounting durability; always check balance and hub engagement after tyre installation to protect drivetrain components.
