The assembly (24) comprises: a first structure (10) extending in a first overall direction (G1), a second structure (12), and a bearing structure (30) comprising filamentary bearing elements (32) comprising at least one filamentary bearing portion (74) extending between the first structure (10) and the second structure (12), the first structure (10) being arranged such that, for a length at rest L of the first structure (10) in the first overall direction (G1), the elongation at maximum force Art of the first structure in the first overall direction (G1) satisfies: Art≤(2π×H)/L, in which H0×K≤H where H0 is the mean straight-line distance between an internal face (42) of the first structure (10) and an internal face (46) of the second structure (12) when each filamentary bearing portion (74) is at rest, and K=0.50.

A wheel for a racing bicycle including a rim with a rim body having a rim well and lateral rim flanks provided with rim flanges, the rim flanges showing bulges protruding inwardly, each defining an undercut at the pertaining rim flange. A tire with two circumferential tire beads is accommodated on the rim body between the rim flanges, the tire beads bearing against the inside of the rim flanges and entering the undercut at the bulges of the rim flanges. A tire retaining device is included which is disposed in the internal space between the tire and the rim well. The tire retaining device includes an insert member having a hollow space that extends between the tire beads and contains a radially outwardly peripheral wall and a radially inwardly peripheral wall, wherein at least the radially inwardly peripheral wall extends continuously across an inner axial width of the insert member.

A tire (1) has improved handling and comprises a stiffening structure (7) comprising two stiffening elements (8), each extending continuously in the toroidal interior cavity (6) from a crown interface (81) connected to a radially inner face of the crown (23) to a bead interface (82) connected to an axially inner face of the bead (41). The stiffening structure (7) is distributed circumferentially around the entire circumference of the tire. The crown interface (81) is positioned, with respect to the equatorial plane (XZ), at an axial distance A at most equal to 0.45 times the axial width S and the bead interface (82) is positioned, with respect to a radially innermost point (I) of the axially inner face of the bead (41), at a radial distance B at least equal to 0.10 times the radial height H and at most equal to 0.5 times the radial height H.

The run-flat tire insert is for use with a wheel having flanges, and a corresponding pneumatic tire having sidewall tire beads with a bead lock edge. The run-flat tire insert includes a deformable annular insert member having a generally U-shaped cross-section with a band portion between opposing leg portions extending radially inward towards the wheel. The deformable annular insert member is made of a fiber-reinforced composite material. The deformable annular insert member is configured as a spring that deflects under load and transmits vertical load forces on the band portion to lateral forces at ends of the opposing leg portions adjacent the bead lock edges of the pneumatic tire against the wheel flanges.
