An aerodynamically honed stem with adjustable length and angle to optimize your position. The rider makes up 80-90% of total aero drag, so refining your position can produce some of the biggest gains of all. Further, the shape of the stem, plus the ability to eliminate headset spacers, allows for cleaner airflow at the front of the bike, producing valuable drag reduction. Created in conjunction with Team Dimension Data, the stem delivers the confident and responsive ride feel demanded by the best riders in the world. This stem is intended for negative drop only and cannot be flipped or reversed in a positive rise. - Material: Carbon - Faceplate Material: Aluminum - Hardware Material: Titanium - Stack Height: 42.5mm with length shim / 45.5mm with angle shim - Torque Spec, Face Plate Upper Bolt: 10Nm, Lower Bolt: 6Nm - Torque Spec, Steer Tube: 5.5Nm

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)

Zipp’s SL Speed stem represents the essence of carbon componentry. It’s stiff, secure, and lightweight with a sleek design that complements any bike.

FSA's K-Force OS-99 CSI is 3-D forged and CNC machined from AL2014 before a uni-directional (UD) carbon weave skin is applied through the Carbon Structural Integration (CSI) process. To further reduce weight the OS-99 uses a 4-bolt sculpted AL2014 alloy/carbon faceplate and titanium hardware. CSI is a process that permanently bonds carbon to alloy, to create a true hybrid product, with many of the benefits of aluminum and carbon. - Stack Height: 41mm - Weight: 126g (100mm)

Your stem may seem inconsequential, but it is the point of transfer between your skilled handling and the bike itself. An impressive refinement of our popular top level Easton alloy stem, the 2019 EA90 stems have an larger boom diameter for increased stiffness and, by utilizing our highest quality alloys, we were able to remove excess material for even more weight savings. We’ve also created a custom computer mount (included with EA90 stems and sold separately) that is compatible with all ICM faceplate stems for cleaner lines and improved aerodynamics. With lengths ranging from 70mm to 130mm, we can accommodate fits for all sizes of frames and riders. We shaved our new EA90 down to 120 grams for a 100mm stem and, with weights like these, we surpass much of the alloy and carbon competition in the market, while giving you the durability, confidence and control you expect from Easton. - Finish: Black Ano - Weight: 120g (100mm) - Rise: +/- 7-deg - Clamp diameter: 31.8mm - Steerer: 1 1/8-inch - Length: 70mm, 80mm, 90mm, 100mm, 120mm - Materials: EA90 alloy - Tech: ICM compatible (faceplate mount included), Top Lock, Taperwall
