ProjectRC MRX7 2-Speed Adaptor | Shaft

ProjectRC, a brand of Italian F.V.S.S, has released this optional MRX7 2-Speed gear adapter featuring a stronger hardening treatment compared to the original Mugen Seiki included part.  The adapter is fully compatible with the original 1:8 Onroad kit’s aluminium shaft, and provides a significant improvement in durability and reliability, eliminating the wear issue in the one-way bearing contact area.  To achieve the ultimate performance, ProjectRC also developed an optional gear shaft which thanks to a deeper and more pronounced hex design on both components is a more precise fit and is much more stable and solid.
