Ritchey WCS 4-Axis Road/Mountain Bike Stem - BB Black - 31.8 x 73 Degree
Tom's original 4-Axis stem changed stem design forever. From the stress-managing forged faceplate, bolt spacing and angled steer tube slot to the now-ubiquitous 3D net forging process, the 4-Axis is still the standard in lightweight, stiff and strong stems.
