This red anodized aluminum adaptor fits Auper D6 wheel setups and provides a consistent seating surface to reduce wear. It serves as a replacement or tuning spacer to change wheel offset and secure wheel mounting on compatible hubs.
Use the part when you need to tweak wheel stance or correct small misalignment during setup. Installation usually involves swapping the original adaptor or hub fittings, then confirming concentric seating and torque on wheel fixings.
Practical notes: check thread compatibility and hub engagement on your Auper D6 before final tightening, verify runout after mounting, and perform a short trial run to confirm handling behavior.
