One of the most modern stem in the market, provided with new patented system D.C.S. (Diagonal Closing System) This fork clamp closing system has been designed in order to avoid extra load in order not to squeeze and stress the carbon fork steerer. Many riders overtighten the screws when the stem moves and often make the steerer brake. The idea is based on the fact that the two clamp work independently with the diagonal instead of in the center as many stems do, This stem is tested and works for road and MTB.
