The reviewer discusses a budget-friendly disc brake mount facing tool kit from China, priced at £50, which uses a grinding disc instead of a cutting head and faces both mounts simultaneously. He demonstrates its use on a bike frame, noting it effectively resolves brake rubbing issues caused by uneven mounts. The tool is aimed at modern road and gravel bikes with 100mm front and 142mm rear axles.
