A drive wheel engaged with flexible track of track apparatus mountable on a vehicle axle, the drive wheel including a peripheral portion which, between radially-extending drive members, has outwardly-facing lug-engagement surfaces in position for engagement with the distal surfaces of the track lugs, to extend the useful life of flexible track. Preferred embodiments have spaces facilitating removal of debris. Certain preferred lug-engaging surfaces are provided by peripherally-spaced cross-members. The drive wheel is preferably free of side structure, allowing track lugs to adjust precise positions of engagement with lug-engagement surfaces. aim 2, wherein each of said first portions has a substantially cylindrical outer peripheral surface and each of said spoke openings has a corresponding substantially cylindrical inner periphery. 8. The bicycle component assembly according to claim 2, wherein each of said abutment surfaces of each of said reinforcement members is formed by two abutment sections located on opposite sides of said first portion. 9. The bicycle component assembly according to claim 2, wherein each of said reinforcement member includes a third portion extending from said first portion to form an additional abutment surface between said first portion and said third portion, each of said additional abutment surfaces facing in an opposite direction to said abutment surfaces between said first and second portions. 10. The bicycle component assembly according to claim 9, wherein each of said first portions has an axial thickness substantially corresponding to an axial thickness of said rim and each of said additional abutment surfaces contacts an external surface of said rim adjacent one of said spoke openings. 11. The bicycle component assembly according to claim 10, wherein each of said third portions is at least partially received a recess of said rim with said additional abutment surfaces contacting said recesses of said rim. 12. The bicycle component assembly according to claim 1, wherein each of said reinforcement members has a spoke hole extending therethrough with one of said spokes received therein. 13. The bicycle component assembly according to claim 12, wherein each of said spoke holes of said reinforcement members is non-circular in transverse cross section. 14. The bicycle component assembly according to claim 12, wherein each of said reinforcement members has a radially extending notch adjacent said spoke holes with one of said spokes at least partially located therein. 15. The bicycle component assembly according to claim 1, wherein each of said reinforcement members includes a pair of curved side surfaces, said first transverse dimension being measured between said curved side surfaces such that said reinforcement members with said outer portions of said spokes coupled thereto pass through said spoke openings in said first relative orientation. 16. The bicycle component assembly according to claim 15, wherein said curved side surfaces of each reinforcement member lie on an imaginary circle that is no greater than said spoke openings. 17. The bicycle component assembly according to claim 16, wherein said curved side surfaces extend between a pair of axial faces of said reinforcement members to form a pair of first edges and a pair of second edges. 18. The bicycle component assembly according to claim 17, wherein said first and second edges are substantially parallel. 19. The bicycle component assembly according to claim 1, wherein said outer annular portion of said rim is free of openings except a single aperture adapted to receive part of a valve therein. 20. The bicycle component assembly according to claim 1, wherein said reinforcement members are integrally formed as one-piece, unitary members with said outer end portions of said spokes. 21. The bicycle component assembly according to claim 1, wherein said reinforcement members are die cast onto said outer end portions of said spokes. 22. The bicycle component assembly according to claim 1, wherein said outer annular portion is substantially U-shaped with a pair of clincher flanges dimensioned to secure a clincher-type tire thereto. 23. The bicycle component assembly according to claim 1, further comprising: a hub coupled to said inner end portions of said spokes. 24. A reinforcement member adapted to be positioned between a spoke and a rim with an outer annular portion, first and second annular spoke attachment portions extending from said outer annular portion and located radially inwardly of said o
