Pipa Ghidon fixa Syncros FL 2.0 D:31.8mm L:50mm Negru - 2505660001109FL2.0 stems are designed to suit the more price conscious road or mountain biker. The stems are 3D forged from an advanced 6061 alloy to achieve the perfect balance of strength, stiffness, and weight, while the broad four-bolt faceplate design better distributes stress and lowers the clamping force required to secure the handlebar.
