I turned to the laboratory to bring my grandfather's bike back to glory, an old iron, very important to me on an emotional level, I found two very skilled and competent technicians who managed to get my bicycle back on the road despite the critical conditions.. .....I can only say thank you very much and congratulations for your dedication, passion, professionalism and courtesy shown
