Competition seatbox with a very light and stable tubular frame. Like the other seatboxes in the HX range, it is equipped with 36mm legs, 4 telescopic and two fixed with threaded bushings, and one with an umbrella holder bush. It has a smaller footprint than the HX500 and HX300 models and features an aluminum profile footrest. Equipped with a module with a side drawer. An excellent product for those who seek compactness and lightness without sacrificing solidity and stability. The trolley kits of the HX series can be used on this frame.
