Know before you buy

While carbon stems may offer slight weight savings and vibration damping, the Elite X4 is machined from a solid block of 7000 series aluminum. This construction prioritizes structural integrity and steering stiffness, making it a preferred choice for riders who value durability and a precise, predictable feel.
Yes, it is important to follow the manufacturer's recommended torque specifications when tightening the faceplate bolts. Using a torque wrench ensures the stem clamps securely without damaging your handlebars or stripping the hardware.
