<p>The present invention concerns a handlebar (11;111;211) for cycles and motorcycles, in particular for cross-country use, which is light but at the same time resistant to high intensity shocks and stresses and having an optimised elasticity, said handlebar comprising a median section (13;113) which presents a central portion (23) having a diameter d23 and a thickness s23 for fixing the handlebar; two end sections (15,17), each of them presenting a central portion (27) having a diameter d27 and a thickness s27 for holding the handlebar; and two intermediate sections (19,21), each of them presenting a central portion (25) having a diameter d25 and a thickness s25 linking to said median section (13) in an inner bending zone (24) and to one corresponding of said end sections (15,17) in an external bending zone (26) having a thickness s26; said handlebar presenting a variable diameter and a variable thickness, characterised in that said thickness and said diameter vary according to the law d23 > d25 > d27 and the thickness of the handlebar varies according to the law s26 > s23 > s25 > s27.</p> |
