CLAIMS
1 . Bicycle fork ( 10 ) comprising
a pair of legs (16) adapted to support for rotation a bicycle wheel (18) , and
a hydraulic braking device including a pair of hydraulic braking actuators (26) , each of which is mounted on a respective leg (16) and is provided with a friction member (38) , wherein each braking actuator (26) is operable to press the respective friction member (38) against a respective braking surface (20a) of a rim (20) of the wheel (18);
characterized in that
each leg (16) has, on the side facing the wheel (18) , a first side abutment surface (24), a first lower support surface (50) and a third front stop surface (52), and in that each braking actuator (26) has a first outer side face (28) arranged against said first side abutment surface (24), a second lower face (32) resting on said second lower support surface (50) and a third front face (34) longitudinally retained in the driving direction by said third front stop surface (52), and a fourth inner side face (30) on which the friction member (38) is mounted.

2. Bicycle fork according to claim 1, wherein said first surface (24) is directly formed by the leg (16) .

3. Bicycle fork according to claim 1 or claim 2, wherein said second surface (50) is directly formed by the leg (16) .

4. Bicycle fork according to claim 1 or claim 2, further comprising a pair of support structures (40) separate from the legs (16) and fixed each to a respective leg (16) , wherein each support structure (40) forms said second and third surfaces (50, 52) .

5. Bicycle fork according to claim 4, wherein each support structure (40) forms also a fourth rear stop surface (54) and wherein each braking actuator (26) has also a fifth rear face

(36) longitudinally retained in the opposite direction to the driving one by said fourth rear stop surface (54) .

6. Bicycle fork according to claim 4 or claim 5, wherein each support structure (40) comprises a L-shaped component formed by a lower support element (42) having said second surface (24) and by a first front vertical stop element (44) having said third surface (52) .

7. Bicycle fork according to claim 6 when depending on claim 5, wherein each support structure (40) further comprises a second rear vertical stop element (46) joined to the L-shaped component (42, 44) on the opposite side to the first element (44) and having said fourth surface (54) .

8. Bicycle fork according to any of claims 4 to 7, wherein each support structure (40) is releasably (48) fixed to the respective leg (16) .

9. Bicycle fork according to claim 7 or claim 8, wherein said second element (46) is rotatably mounted about a longitudinal axis (56) with respect to the L-shaped component (42, 44) , in such a manner that it can be moved between a first position in which said fourth surface (54) of the support structure (40) retains longitudinally the respective braking actuator (26) , and a second position in which said fourth surface (54) allows the longitudinal movement of the respective braking actuator (26) in the opposite direction to the driving one .

10. Bicycle fork according to any of the preceding claims, wherein each first surface (24) is arranged at such a height that it faces the associated braking surface (20a) when the wheel (18) is mounted on the fork.

11. Bicycle fork according to any of the preceding claims, wherein each first surface (24) is inclined (OC) to a vertical plane of symmetry of the fork so as to converge in the driving direction.

12. Bicycle fork according to any of the preceding claims, wherein said second face (32) of each braking actuator (26) has a longitudinal groove and said second surface (50) of each leg (16) forms a guide projection which engages in the above-mentioned longitudinal groove.

13. Bicycle fork according to any of claims 1 to 11, further comprising, for each leg (16) , a guide edge cooperating with said fourth face (30) of the respective braking actuator (26) to retain this latter in the transversely inner direction.

14. Bicycle fork according to claim 1, comprising a pair of abutment elements, each of which is interposed between a respective leg (16) and a respective braking actuator (26) and forms said first surface (24) .

15. Bicycle fork according to any of the preceding claims, wherein the legs (16) have on their inner sides grooves suitable for receiving at least partially supply conduits of the braking actuators (26) .
