A submersible article comprises a buoyancy body formed from polyurethane foam having a first density, which is at least partly overmolded with a protective skin of polyurethane foam having a second density higher than the first density. The lower density foam of the body gives the article buoyancy,
A submersible article comprises a buoyancy body formed from polyurethane foam having a first density, which is at least partly overmolded with a protective skin of polyurethane foam having a second density higher than the first density. The lower density foam of the body gives the article buoyancy, while the higher density protective skin strengthens the article and gives impact resistance. The protective skin can be stiffened, either uniformly or locally, by the addition of glass fiber or other reinforcing material which is arranged over the buoyancy body prior to the overmolding. The article can be made by a two-stage molding process.

The handlebar of claim 1, wherein the tensile strength of the rod is greater than the tensile strength of the tubing. 8. The handlebar of claim 1, wherein the rod increases the stiffness of the handlebar. 9. The handlebar of claim 1, further comprising an adjustable dampening mechanism to controllably tension the rod. 10. The handlebar of claim 1, wherein the tubing is an integral titanium tube. 11. The handlebar of claim 1, wherein the central region, the first bent region, and the first handgrip region form a first span, the first span supported at only the central region, and wherein the central region, the second bent region, and the second handgrip region form a second span, the second span supported at only the central region. 12. The handlebar of claim 1, wherein the outer diameter of the tube is 7/8 inch. 13. A handlebar for a vehicle, comprising: a tubing comprising: a central region having a first end and a second end; a first handgrip region extending from the first end of the central region, the first handgrip region adjoined to the first end of the central region by a first bent portion; and a second handgrip region extending from the second end of the central region, the second handgrip region adjoined to the second end of the central region by a second bent portion; and a rod disposed within the tubing, the rod contacting an inner wall of the tubing at the first and second bent portions. 14. The handlebar of claim 13, wherein stiffness of the handlebar is adjustable by varying rod tension. 15. The handlebar of claim 13, further comprising: a first rod restraint secured at the first handgrip region, the first rod restraint coupled to one end of the rod; a second rod restraint secured at the second handgrip region; and an adapter coupling the rod to the second rod restraint. 16. The handlebar of claim 15, further comprising: a bias member coupling the adapter to the second rod restraint; wherein the bias member drives the adapter; and wherein the position of the adapter determines rod tension. 17. The handlebar of claim 16, wherein the bias member is a screw, and wherein rod tension is adjusted by rotating the screw. 18. The handlebar of claim 17, wherein contact forces between the rod and the tubing at the first and second bent portions increases as rod tension is increased. 19. The handlebar of claim 13, wherein the tensile strength of the rod is greater than the tensile strength of the tubing. 20. The handlebar of claim 13, wherein the rod increases the stiffness of the handlebar. 21. The handlebar of claim 13, further comprising an adjustable dampening mechanism to controllably tension the rod.
