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.

All Box stems are engineered and crafted using our Oversized Technology. As we follow the load paths down the handlebars we have focused our attention on the stem-to-bar interface. Since the Oversized handlebars have an increased wall thickness and tube diameter in this sector we have reciprocated with an augmented stem interface with greater surface area. We’ve done this by moving material from low stress areas. This has greatly minimized twist and contributed to responsiveness. As the stem in mated with the handlebars we have contributed to increased pedaling stiffness by providing a backstop to the “lifting” phenomenon. There is no point pushing hard on your pedals if you can’t pull up on your handlebars and deliver that power. Power can easily be lost to handlebar-to-stem deflection and the consequences can be poor power delivery and steering control. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency.
Key differences: In this particular model stem we’ve modulated the Oversized formula to emphasize pedaling stiffness. We have transferred material specifically to sectors that experience sudden stress from pulling up on the handlebars. You’ll feel a difference in your acceleration. These stems are engineered for the larger-sized racers.

Hollow stems are cold forged from the highest quality 6061-T6 aluminum available. Featuring an open skeletal design and a dual mid-bolt wedge mounting system, they are lightweight yet maintain a very high level of strength. A 53mm extension stem weighs just 218 grams/7.7 ounces. By removing the rear pinch bolts and moving the mounting bolts to the middle of the stem, we reduced the weight and size and eliminated a serious hazard to the rider’s knees.
These stems come with either a 48- or 53mm extension and a 22.2mm bar bore. To ensure proper clamping force, the stem must be mounted on a fork with at least 45mm of exposed steerer tube. Not compatible with forks that have carbon fiber steerer tubes.

You really can have it all-the WCS C220 stem rivals the performance of the revolutionary C260 stem design, but it's quicker and easier to install and remove thanks to a press-fit handlebar clamp interface and forward-facing hardware. The WCS C22 73D Stem offers 17-degrees of positive or negative rise. First proven on the Ritchey Trail Stem, the C220 handlebar clamp design creates a more secure interface by wrapping a full 220 degrees over the handlebar. Bolt forces are aligned with the clamp so that the stem body 'embraces' the handlebar, which is less prone to damaging lightweight bars. This clamp design allows for a lighter faceplate and stem body with no sacrifice in strength or stiffness. The stem body is forged 2014 aluminum for further weight reduction. Premium quality CrMo steel bolts are used throughout.
- Material: 3D forged 2014 alloy body
- 4 x 4mm coated CrMo steel forward-facing faceplate bolts
- 2 x 4mm coated CrMo steel offset steer tube clamp bolts
- 5Nm torque max on all hardware
- Compatible with all 31.8mm bars
- Press-fit clamp design installs and removes like a standard stem
- Angle: 73/17 degree
- Stack: 45mm
- Steerer: 1-1/8"
- Faceplate Width: 42mm
- Blatte 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.

Taking cues from the legendary Ritchey Bullmoose mountain bike bar, as well as more recent Ritchey road combo bars such as the SoloStreem and MonoCurve, the SuperLogic Butano Ridge fills the demands of adventurous riders calling for a carbon fiber version of the Butano. We’ve doubled down on the original concept of the Butano by blessing it with the SuperLogic treatment and delivering an integrated bar/stem combo that is lightweight, stealthy, and more than capable of handling the rough stuff when it turns into fast rough stuff. This magnificent monocoque carbon fiber beauty offers complete internal cable/wire/hose routing for modern gravel and road bike frames. The underside of the bar features a removable cable cover offering easy access for cable routing and doubles its duty with the ability to receive an integrated accessory mount (sold separately). The breathtaking aesthetics of the Butano Ridge are well complimented by its supreme comfort and control afforded by its shallow drop, short reach, and pleasant backsweep – as well as the ergo aero tops that deliver logical ergonomics.
