M-Way Menabo Roof Bars These M-way branded universal aluminium roof bars come as a pair. They are suitable for mounting universal roof boxes, cycle carriers, kayak carriers etc. These silver aluminium bars not only looks smart but they are aerodynamic, giving you a smooth and eco friendly drive with them attached. A minimum of 2 cm clearance between the rails and roof is required, and so these bars are not suitable for flush mounted roof rails.
