Algi is a French company founded in 1923, specialising in fasteners and workshop equipment. In the bicycle industry, it mainly supplies small fastening parts: cable clamps, adjustment barrels, nuts and washers. Its products are intended for maintenance and repair rather than for the manufacture of complete groupsets. Renowned for its reliability and availability, it still equips many vintage bicycles. Today, Algi remains active in the supply of mechanical accessories for bicycles and industry.
