Soyo Gold Star NJS Seamless Tubular Tyre, the only tubular tyre authorised for use in the Japanese JKA Keirin Series and hence it has been awarded the NJS approval mark.

Soyo is the brand name for the tyres manufactured by Daiwabo, a Japanese company who specialise in very, very high end textile manufacture. It's allowed them to produce a seamless tubular tyre with an effective TPI of over 1000, constructed using a latex tube will a wall thickness of less than 0.35mm that has incredibly uniformity.

Soyo seamless tubular tyres are unlike any other tubular tyre from other manufacturers. Soyo seamless tyres are produced in a unique way by directly winding the thread of the casing on to the tube, thereby eliminating the sewing and gluing process “ the world's only seamless tubular.

This manufacturing process allows the tubular to be constructed with a perfect round/circular cross-section resulting is a huge improvement in the following areas of performance:

¢ Rolling resistance
¢ Grip
¢ Power
¢ Superior ride comfort

Performance at this level comes at a price, so Soyo tubulars are recommended for use for events where the benefits of using such a tyre are needed, regardless of cost.
