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.
Stem angle is one of the factors that determines handlebar height. A listed angle of 0 degrees actually provides a rise that is dependent on your bike’s head angle (see image).
Stem length is measured along the side of the stem from the center of the steerer to the center of the handlebar clamp (see diagram). Keep in mind that as a stem provides more rise, its effective length decreases. In the example above, if the +17 degree stem measures 135mm, it actually extends 108mm parallel to the ground.
