Soyo is the brand name for the tyres manufactured by Daiwabo, a Japanese company who specialise in very, very high end textile manufacture. All Soyo seamless tyres are produced in a unique way by directly winding the thread of the casing on to the tube, hence eliminating the sewing and gluing process which is dubbed the 'world's only seamless tubular'.
