Stem length and angle get most of the attention during bike fitting, but clamp diameter matters just as much for riders running modern oversized steerer tubes. The Ritchey WCS C220 Stem addresses the 1-1/4" steerer standard that appears on certain gravel and adventure bikes, providing a dedicated clamping solution rather than forcing riders to use shims or adapters with standard 1-1/8" stems. This isn't a universal stem—it's purpose-built for frames specifying the 31.8mm (1-1/4") steerer diameter, which sits between the common 1-1/8" road standard and the 1.5" lower headset cups found on tapered setups.

The C220 designation refers to Ritchey's two-bolt face clamp design, which uses opposing bolts to distribute clamping force evenly around the handlebar. This matters more than you might expect—uneven bolt tension can stress handlebars and create creaking at the stem interface, particularly with carbon bars where torque specifications are tighter. The four-bolt steerer clamp follows the same logic, spreading load across the steerer tube rather than concentrating it at two points.

WCS-grade 3D forged aluminum construction keeps weight reasonable while maintaining the stiffness that performance-oriented riders expect from their cockpit. The 84-degree stem angle translates to a 6-degree rise from horizontal when installed in the standard position, though flipping it over gives you a 6-degree drop if you're after a more aggressive position. Ritchey finishes the stem in their Blatte colorway, which pairs cleanly with black or dark component builds.... Read More
