A reinforced product () comprises: an elastomer matrix (), several reinforcing elements () embedded in the elastomer matrix (), the reinforcing elements () being arranged side by side in a main direction (X). Each reinforcing element () comprises: at least one filamentary element, and at least one sheath coating the filamentary element and comprising at least one layer of a thermoplastic polymer composition. The ratio R1=ODO/E of the mean minimum thickness ODO of elastomer present on the back of the sheath to the mean thickness E of the reinforced product () is less than or equal to 0.17.

Thin reinforced product and tire comprising said product

Bicycle tire () comprising a continuous toothing () having a substantially radial generatrix (G) with respect to the rotation axis of the tire in the axial direction (YY'), said toothing () being positioned circumferentially on an axially outer face () of at least one sidewall () and comprising an elastomeric material. A retroreflective strip () is positioned circumferentially on the sidewall (), axially on the outside of the axially outer face () of the sidewall () and radially on the outside of the toothing (), a strip support () is interposed axially between the retroreflective strip () and the axially outer face () of the sidewall (), and an axially outer face () of the strip support (), to which the retroreflective strip () is applied, forms an angle (A) of at most equal to 30&#xb0; with the radial direction (ZZ&#x2032;) of the tire.

Bicycle tire

The tire (B) comprises a tread () including a running layer () which is intended to come into contact with the ground when the tire (B) rolls on the ground, and a sublayer () located radially inwards from the running layer (). The tread () comprises at least one fluid passage () between the sublayer () and the air surrounding the tire (B). The sublayer () comprises a cellular material. The fluid passage () comprises an element chosen from a groove () and a cut (), formed in the running layer () and extended by at least one well () acting as a radial extension of the element, formed between the groove () and/or the cut () and the sublayer (). Each well () forms a localized part of the fluid passage ().
