The outer axle has a first threaded end and a second end. The inner axle is coupled to the outer axle within an internal bore of the outer axle. The head member is disposed on the inner axle with the lever member operatively mounted to move the head member relative to the inner axle in response to movement of the lever member. A structure is arranged such that a final rotational position of the lever member can be adjusted. A structure is also disposed between the outer axle and the inner axle to releasably prevent axial removal of the inner axle from the internal bore of the outer axle. ## Claims ### Claim 1 A bicycle wheel securing structure comprising: an outer axle having a first threaded end and a second end with an internal bore extending from the second end; an inner axle threadedly coupled to the outer axle within the internal bore of the outer axle in an installed position; a head member disposed on an end of the inner axle extending out of the internal bore at the second end of the outer axle; and a lever member operatively mounted to move the head member in an axial direction relative to the inner axle in response to movement of the lever member; and an adjustment structure disposed between the outer axle and the inner axle such that a final position of the lever member in a rotational direction can be adjusted when a bicycle wheel is fully secured to a bicycle frame. ### Claim 2 (depends on 1) The bicycle wheel securing structure according to claim 1, wherein the adjustment structure includes an adjustment element releasably coupled between the outer axle and the inner axle to prevent relative rotation therebetween. ### Claim 3 (depends on 2) The bicycle wheel securing structure according to claim 2, wherein the adjustment element includes a set screw arranged in a transverse threaded bore of the outer axle, the transverse threaded bore extending between an external surface of the outer axle and the internal bore such that the set screw is releasably engageable with the inner axle. ### Claim 4 (depends on 3) The bicycle wheel securing structure according to claim 3, wherein the inner axle includes at least one adjustment opening that removably receives a portion of the set screw. ### Claim 5 (depends on 4) The bicycle wheel securing structure according to claim 4, wherein the inner axle includes a plurality of circumferentially spaced adjustment openings arranged to selectively removably receive the set screw in a plurality of different rotational positions. ### Claim 6 (depends on 2) The bicycle wheel securing structure according to claim 2, wherein the inner axle includes at least one adjustment opening that removably receives a portion of the adjustment element. ### Claim 7 (depends on 6) The bicycle wheel securing structure according to claim 6, wherein the inner axle includes a plurality of circumferentially spaced adjustment openings arranged to selectively removably receive the adjustment element when the inner axle is located in a plurality of different rotational positions relative to the outer axle. ### Claim 8 (depends on 1) The bicycle wheel securing structure according to claim 1, wherein the first threaded end of the outer axle has an O-ring mounted thereon to prevent accidental loosening of the first threaded end when attached to a threaded mating member. ### Claim 9 (depends on 8) The bicycle wheel securing structure according to claim 8, wherein the O-ring is constructed of a resilient material ### Claim 10 (depends on 1) The bicycle wheel securing structure according to claim 1, wherein the inner axle is constructed of an iron alloy, and the outer axle is constructed of an aluminum alloy. ### Claim 11 (depends on 10) The bicycle wheel securing structure according to claim 10, wherein the outer axle has an outer maximum axial length, and the inner axle has an inner maximum axial length less than one-half of the outer maximum axial length. ### Claim 12 (depends on 1) The bicycle wheel securing structure according to claim 1, wherein the outer axle has an outer maximum axial length, and the inner axle has an inner maximum axial length less than one-half of the outer maximum axial length. ### Claim 13 A bicycle wheel securing structure comprising: an outer axle having a first threaded end and a second end with an internal bore extending from the second end; an inner axle threadedly coupled to the outer axle within the internal bore of the outer axle in an installed position; a head member disposed on an end of the inner axle extending out of the internal bore at the second end of the outer axle; and a lever member operatively mounted to move the head member in an axial direction relative to the inner axle in response to movement of the lever member; a fixing structure disposed between the outer axle and the inner axle to releasably prevent axial removal of the inner axle from the internal bore of the outer axle when the inner axle is in the installed position; and an adjustment member axially adjustably coupled to the head member such that a final position of the lever member in a rotational direction can be adjusted when a bicycle wheel is fully secured to a bicycle frame. ### Claim 14 (depends on 13) The bicycle wheel securing structure according to claim 13, wherein the fixing structure disposed between the outer axle and the inner axle is arranged and configured to releasably prevent relative rotation of the inner axle within the internal bore when the inner axle is in the installed position. ### Claim 15 (depends on 13) The bicycle wheel securing structure according to claim 13, wherein the fixing structure includes a set screw arranged in a transverse threaded bore of the outer axle, the transverse threaded bore extending between an external surface of the outer axle and the internal bore such that the set screw is releasably engageable with the inner axle. ### Claim 16 (depends on 13) The bicycle wheel securing structure according to claim 13, wherein the inner axle includes a smooth outer surface section and the set screw of the fixing structure releasably frictionally contacts the smooth outer surface section to prevent relative rotation between the outer axle and the inner axle. ### Claim 17 (depends on 13) The bicycle wheel securing structure according to claim 13, wherein the inner axle is constructed of an iron alloy, and the outer axle is constructed of an aluminum alloy. ### Claim 18 (depends on 17) The bicycle wheel securing structure according to claim 17, wherein the outer axle has an outer maximum axial length, and the inner axle has an inner maximum axial length less than one-half of the outer maximum axial length. ### Claim 19 (depends on 13) The bicycle wheel securing structure according to claim 13, wherein the outer axle has an outer maximum axial length, and the inner axle has an inner maximum axial length less than one-half of the outer maximum axial length.
