Stems

On today's road bikes, silver stands out amid the sea of stealthy black color schemes. This time-honored color is available on the Zipp Service Course stem. Since the introduction of our line of Service Course and Service Course SL components, we've had amazing success with our pro-level athletes in all disciplines. While the successes have reinforced our design decisions, we have also drawn from their feedback. We not only learned how and why athletes make their equipment choices, but how our manufacturing methods and materials affect product performance. With new knowledge as well as new engineering methods, we are proud to introduce our completely redesigned line of Service Course and Service Course SL stems. - Class-leading stiffness-to-weight ratio - More options for a better fit - New faceplate and geometry for greater stiffness and easier installation - Distinctive silver finish

The new Ritchey WCS Toyon stem takes its lead from the original, award-winning Ritchey C220 stem and gives it a more modern shape and increased stiffness for improved handling and greater responsiveness. The Toyon retains the clamping surface area of the C220, which creates a more secure interface by wrapping a full 220° over the handlebar. Its bolt forces are aligned with the clamp so that the body "embraces" the handlebar—a design which is less prone to damaging lightweight bars and allows for a lighter faceplate and stem body with no sacrifice in strength or stiffness. Built from life and all that inspires it, the Toyon builds upon the proven and celebrated C220 design with a fresh, squared aesthetic that adds to the overall harmony of modern frame designs—matching its good looks with enhanced confidence and a more lively feel for wherever your rides take you. - Matching top cap included - 6° of positive or negative rise - 1-1/8" steerer diameter - Stem body wraps 220° around bar clamping area, holding it in place for easy installation - Material: 2014 alloy - Bolts: stainless steel black - Matching top cap included - Angle: 84°/6° - Bar clamp diameter: 31.8mm - Bar clamp width: 44mm - Steerer diameter: 1-1/8" (28.6mm) - Steerer height: 42mm - Weight: 140g (100mm)
