The Turbine 35 stem was designed to reduce overall system weight while retaining the proven stiffness and performance the Race Face line is known for. The stem itself is measurably stiffer than the 31.8mm offering and, although the system is a seemingly burlier build, the weight savings gained by the reduction in bar material actually makes the 35 system lighter overall.
