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

Zipp's Service Course SL Stem, crafted from 7075 aluminum, features a shape that's strong and lightweight, resulting in a best-in-class 1.85 grams per newton meter of stiffness. That results in no-flex sprints and accelerations. This stem is a favorite of Zipp ambassadors and pro athletes. - Distinctive Zipp cosmetics - Zipp Quickview integrated computer mount available separately - Lifetime warranty

The Ritchey WCS Trail Stem represents Ritchey's first stem specifically designed for today's 5-6-inch travel trail bikes using wide bars. More than just a beefed-up version of other stems, with the Trail stem we revised the patented C260 clamp to a 220-degree version that fits a wider variety of riser bar bends and still packs a dramatic increase in stiffness and strength over competitor's designs. Using 3D Forged 2014 alloy, the WCS Trail Stem serves up superior strength while remaining lightweight. The extra-wide bar clamp takes stiffness to the next level, fits most riser bars, and ensures plenty of confident control out on the trail. - Material: 3D Forged 2014 alloy - Angle: Zero rise - Steerer Height: 45mm - Faceplate Width: 40mm - Steerer: 1-1/8” - Ritchey Blatte finish - 115g (70mm)

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 84D Stem offers 6-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: 84/6 degree - Steerer Height: 42mm - Faceplate Width: 42mm - Blatte finish - 121g (110mm)

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.
