ABSTRACT:
The invention relates to a front fork (10) for cycles, made of composite material, comprising two fork arms (12, 14) which unite to form an upper fork head (18). The fork head (18) comprises two rearwardly directed projections, an upper projection (30) and a lower projection (28). The two projections carry pivot portions (36, 38) which cooperate with complementary pivot portions (32, 34) provided on the steering head (24) of the frame. The fork arms (12, 14) are formed substantially linear and their centrelines are arranged at least generally in a plane in which the centreline of the fork head (18) also extends. This plane is located forwardly of the steering axis (YY) at a distance which depends on the dimensions of the cycle and is suitable to ensure the stability of the cycle.
