The Foil Aero stem is designed to be perfectly integrated into the new SCOTT FOIL bike. The optimized design achieves the perfect balance of strength, stiffness and weight while maintaining the smoothest and cleanest design. The body is forged from strong 6061 aluminum, while the broad four-bolt face plate design better distributes stress and lowers the clamping force required to secure the handlebar. Note this is an 1 1/4 inch steerer mounting.
