With its 3D-forged aluminum construction, 4-bolt faceplate, and titanium hardware, Giant's Contact OD2 Stem is a great way to add lightweight strength and a custom fit to your ride. The oversize box cross-section gives you stiffness that you can feel when you really torque on the bars. The recessed top cap and integrated upper spacer give you a clean, streamlined look that increases the steerer interface for a super solid front end. This stem is compatible with Giant's OverDrive 2 1-1/4-inch fork steerers as well as standard 1-1/8-inch steerers.
