    Abstract: A tyre for bicycle wheels, having a carcass structure, a belt layer arranged in a radially outer position with respect to the carcass structure and a tread band arranged in a radially outer position with respect to the belt layer. The carcass structure has a carcass ply engaged with a pair of annular anchoring structures and including a plurality of reinforcing cords. The cords are inclined, with respect to an equatorial plane of the tyre, at a first angle between about 65° and about 90°. The belt layer has a reinforcing cord wound onto the carcass structure according to a winding direction oriented, with respect to the equatorial plane, at a second angle between about 0° and about 30°.

    Abstract: A motorcycle tyre intended to be fitted to the rear wheel of a motorcycle. The motorcycle tyre has a tread pattern with a high void-to-rubber ratio that provides a suitable draining. The tread pattern has pairs of primary grooves to carry out the draining function of the tyre, and arranged substantially according to the stress lines of the tyres to reduce the probability of triggering uneven wear. Also included are secondary grooves having a reduced dimension, in terms of both extension and width, arranged between the primary grooves to increase the grip of the tyre to the ground. Orientation of the secondary grooves increases stabilizing features against drift forces acting on the tyre, particularly in low or very low friction conditions.

    Abstract: A tyre that can be fitted to the front of a motorcycle. The tyre has a high void-to-rubber ratio and includes grooves located asymmetrically across the equatorial plane of the tyre, arranged substantially orthogonally to the equatorial plane of the tyre at the equatorial plane itself. According to one aspect, the grooves are close to one another in the circumferential direction of the tyre to increase their number in a footprint area of the tyre.

    Abstract: The present invention relates to a tyre for bicycle wheels comprising a tread band containing an anti-puncture system capable of offering high resistance to the penetration of foreign bodies. In particular, the present invention relates to a tyre (100) for bicycle wheels comprising: —a carcass structure (2); and —a tread band (7) arranged in a radially outer position with respect to said carcass structure (2); characterised in that said tread band (7) is made by vulcanisation of a vulcanisable elastomeric compound comprising fibrillated polymeric fibres of micrometric dimensions, wherein at least one protective layer (6, 11) is interposed between said carcass structure (2) and said tread band (7), said protective layer (6, 11) comprising (i) a plurality of reinforcing cords of textile material oriented with respect to the equatorial plane of the tyre with an angle greater than 30°, (ii) a square fabric with textile fibres of the weft or warp oriented with respect to the equatorial plane of the tyre with an angle greater than 20°, or (iii) a non-woven fabric with randomly oriented textile fibres.
