Abstract:
A bicycle wheel rim comprising:an annular spoke-mounting wall having two annular lateral peripheral edges;spaced left and right annular tire-retaining walls extending integrally, radially, outwardly, and respectively from said lateral peripheral edges of said spoke-mounting wall, each of said tire-retaining walls having an inner surface facing the other one of said tire-retaining walls to confine a tire receiving space therewith, an outer brake pad contacting surface opposite to said inner surface, and an annular end face distal to said spoke-mounting wall, each of said tire-retaining walls further having a tire retaining projection formed at and protruding from a corner of said end face and said inner surface and adapted to engage a bicycle tire so as to retain the bicycle tire between said tire-retaining walls, each of said tire-retaining walls further having an outer projection formed at and protruding from a corner of said end face and said outer brake pad contacting surface; anda pair of wear-resisting rings made of a resilient material, each of said wear-resisting rings extending along said end face of a respective one said tire-retaining walls and projecting radially and outwardly relative to said end face of the respective one of said tire-retaining walls so as to be adapted to prevent said end face from contacting directly the bicycle tire to minimize wearing of the bicycle tire;wherein said end face of each of said tire-retaining walls is formed with an annular retaining groove therealong, each of said wear-resisting rings being received in said annular retaining groove in said end face of the respective one of said tire-retaining walls, said annular retaining groove being formed between said tire retaining projection and said outer projection.
