The roof shaft has been designed as a component that works with the original BMW soft top mechanism. The black color promotes visual consistency with other parts of the structure, which is important for both servicing and subsequent inspections.

• easy fitting to the existing structure,
• compatibility with original guides and arms,
• the possibility of installation in place of a worn or damaged part.
