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

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.

The WCS C220 stem is easy to install and remove thanks to a press-fit handlebar clamp interface and forward-facing hardware. - The 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 - Clamp design allows for a lighter faceplate and stem body with no sacrifice in strength or stiffness

For cross country and all-mountain riding, Dimension Trail Stems provide a broad array of sizing options, rigorously tested to ISO 4210 Mountain standards. - Constructed with AL-6061-T6 aluminum - Shot-peened finish - Dimension stems are not intended for use with carbon handlebars or carbon steerer tubes

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 tailored the Oversized strategy to favor utility and access. The geometry has been altered to allow for easy handlebar removal while at the same time scavenging material from low stress zones. Ideal for those who don’t want to compromise on user experience to gain performance. These stems are engineered for the larger-sized racers.
