Stems

Zipp's Service Course Stem is strong, light, and reliable. Forged of 7075 aluminum with stainless steel bolts, the Service Course is stiff enough to harness the power of your burliest sprints and withstand the jarring forces of the meanest potholes. It keeps the front end completely rigid, providing control no matter the condition.

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 TLO Carbon stem is the perfect fit for all Schmolke Carbon handlebars. Tried and tested for Road, Cyclocross and X-country up to a maximum rider weight 220Lbs. Rather than going the simple way by holding the aluminum nuts by a half round bent plate we are using the “loop technology” where the carbon fibers run fully around the aluminum inserts – allowing for full stiffness. Expect zero noise even at low torque.

At just 103 grams, Ritchey's C-260 is among the lightest stems in the world. This revolutionary design starts with a handlebar clamp that wraps a full 260 degrees around the bar to distribute clamping stress evenly through the handlebar, faceplate, hardware and stem body. The steerer tube clamp uses three bolts and a curved slot to reduce clamp stress on the steer tube. So you can run carbon bars and a carbon steerer no problem. Weight and stiffness were prime considerations; the C-260 is 3D forged from 7050 aluminum and machined, even the steel M4 bolts shave a few grams with no sacrifice in strength or rigidity.

The ENVE Road Stem is a staple component in our line and often under-appreciated for the benefits it provides out on the road. The stem plays a key role by connecting your bike to your handlebars and it must manage all the forces that you put into your bike. On the road, the 100% uni-directional carbon body provides a lightweight structure that is torsionally and laterally stiff to ensure that inputs into steering and accelerating are positive and confidence-inspiring. Over rough roads, the carbon fiber laminate helps absorb vibration and reduce hand and upper body fatigue. To further reduce weight, all stem hardware is constructed from lightweight titanium. The faceplate is cold-forged aluminum that allows for a highly reliable and strong grip on the handlebar for responsive steering input with zero slipping. - Material: Carbon Fiber - Faceplate Material: Aluminum - Hardware Material: Titanium - Stack Height: 41mm - Torque Spec, Face Plate: 5.5Nm - Torque Spec, Steer Tube: 5.5Nm - Weight: 90g (80mm), 107g (90mm), 115g (100mm), 121g (110mm), 126g (120mm), 136g (130mm), 145g (140mm)
