Abstract:
1. A rim for a bicycle wheel comprising a body with a substantially continuous annular extension having a radially outer portion shaped for the coupling with a tire, said radially outer portion comprising a hole for an inflation valve having a widened head, said hole constituting a first surface discontinuity along the substantially continuous annular extension of said radially outer portion, wherein said radially outer portion comprises, in an area proximal to said hole, at least one cross section having a different cross section from that at an area distal from said hole, so that the at least one cross section forms at least one second surface discontinuity along the substantially continuous annular extension of said radially outer portion, wherein said at least one second surface discontinuity prevents the rotation of said inflation valve about its own longitudinal axis through contact with said widened head.
