Tom Ritcheys 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.
WCS (WORLD CHAMPIONSHIP SERIES) - These words evoke the core philosophy behind Ritcheys highest performance components. The rainbow stripe WCS logo represents the numerous world champions that have won on Ritchey. The WCS line is the gold standard for lightweight, bombproof race parts and cutting edge innovation.

Rated 4 out of 5 by RoadRider78 High quality finish, but poor bolts.
The only issue I have with this product is the bolts seem to be made of a steel that is too "soft".
Also, it's as if they are very slightly larger than 4mm. I have tried a number of high quality tools, and they all exhibit play. It is easy to slip and damage the head.
Be careful when installing. Also, the bolts have a beveled washer so cannot be replaced with bolts sourced from anywhere other than Ritchey.
