A tyre (100) for racing bicycle wheels comprises a carcass structure (2) and a tread band (6) arranged in a radially outer position with respect to the carcass structure (2); wherein the carcass structure (2) comprises a single carcass ply (3) turned around annular anchoring structures (4a, 4b) and wherein free edges (11) of the carcass ply (3) are radially juxtaposed over one another. A protective layer (16) has a width equal to or less than 50% of the width of the tyre (100). A first sidewall reinforcing ply (14) and a second sidewall reinforcing ply (15) are axially arranged between a respective annular anchoring structure (4a, 4b) and an equatorial plane (X) of the tyre. In a first area of juxtaposition (17), the protective layer (16), the first sidewall reinforcing ply (14) and the portion of juxtaposition (12) of edges of carcass ply are radially juxtaposed according to a predetermined order. In a second area of juxtaposition (18), the protective layer (16), the second sidewall reinforcing ply (15) and the portion of juxtaposition (12) of edges of carcass ply are radially juxtaposed according to a predetermined order. The first area of juxtaposition (17) and the second area of juxtaposition (18) are arranged at respective distances from the equatorial plane (X) comprised between 3% and 24% of the width of the tyre (100).
