The Peruzzo Siena 669 rack features a quick connection system suitable for most types of hooks, without the need for additional adjustments. The detachable support arms can be easily mounted and removed, reducing the time required to secure the bicycles on the rack. With a rubber contact surface for protecting the bicycles, it can hold frames up to 80mm. The Siena 669 cannot be folded with bicycles installed. It includes a license plate holder that incorporates brake lights and turn signals. These can be connected to the vehicle's electrical system via a 13-pin socket or optionally via a 7-pin system using an adapter.
