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

Strong, light and elegant. Chromag's longest running stem, the Ranger, has a refined body shape that represents their own advancement in 3D modelling and CNC profiling. The Ranger is stronger and stiffer for today’s increased demands with blended body features to increase performance with a more fluid look. The Ranger evolves with the same physical fundamentals, more flow, and increased strength. Starting at 140g, the Ranger is light yet extremely stiff for positive control at the front end.

Syntace's Megafroce 2 stem is intended for all-mountain and downhill riding and comes in a range of sizes with a focus on torsional stiffness and weight savings. The 42mm wide bar clamp area stiffens up cockpits with bars wider than 700mm Titanium bolts help keep the weight low and strength high. - Stack height: 36mm - Weight: 132g (70mm)

3T's Arx II is a subtle refresh of the well-liked Arx alloy stem, which has found a place on every sort of bicycle since its launch in 2007. The faceplate is drawn in tighter at top and bottom for a more ovalized frontal appearance, while retaining the cutout 3T logo. The sides of the extension are slightly flattened for a more sculpted look by comparison with the tubular section of the first-generation Arx. A single M7 bolt clamps the stem to the fork steerer, instead of the twin M5 bolts previously used, and the Allen bolts used on the original Arx have been replaced by no-strip Torx bolts. - Stack height: 40mm - Weight: 135g (110mm)

RaceFace designed their Atlas 35 stem to reduce overall system weight while retaining the proven stiffness and performance the Atlas line is known for. The stem itself is measurably stiffer than the 31.8mm offering and, although the system is a seemingly burlier build, the weight savings gained by the reduction in bar material actually makes the 35 system lighter overall. An impressively light, strong addition to your aggressive trail or DH/FR build. - Four-bolt bar clamp holds bar securely in position - Interlocking U-Shaped Handlebar Clamp Geometry - Faceplate eliminates stress risers which cause your bar to bend or break - Opposing bolts on steer tube clamp provides extreme clamping power while reducing stress on the steer tube - Stack Height: 40mm

Renthal's revolutionary Integra stem combines high strength with ultra-low weight. The use of two independent, C-shape handlebar clamps allows the stem body material to be reduced to a minimum, while maintaining an incredibly stiff and strong structure. The ultra-wide, 64mm handlebar clamping area increases torsional rigidity and the use of just six bolts vastly reduces overall weight. In addition, the uninterrupted clamp on the underside of the handlebar eliminates stress risers found on most other clamps, which can lead to handlebar failure.

Mass is the enemy of performance, so we pulled out all the stops to make the Alpinist Cockpit the lightest one-piece bar/stem combo that passes our standards; at 255 grams (110 mm x 420mm). Not only does light weight make for faster climbing, it also improves acceleration and ride quality. The Alpinist Cockpit's round tube shape and tradition bend respect tried and true forms, but the optimized composite layup and internal cable routing are decidedly modern. Available in 10 sizes, there's one that will fit you perfectly. And because they are backed by a no-fault crash replacement policy and lifetime warranty, you can rest easy knowing that we've got your back. - Bend: Tradition radius ( 125mm Drop / 75mm Reach) - Clamp Diameter: 31.8 - Compatibility: Shimano, SRAM, Campagnolo; Di2 and EPS - Material: Advanced carbon composite - Sizes: 400 mm x 80/90/100mm; 420mm x 90/100/110/120mm; 440mm x 110/120/130mm - Stem Angle (Rise): 6-Degrees - System Weight Limit: 275lbs / 125kg - Weight: 255 grams (110 mm x 420 mm)

With its classic blend of high strength and low weight, Easton's EA50 stem is a smart choice for your favorite ride. It's made of 3D forged aluminum for amazing stiffness and strength. Easton's Top-Lock technology locks the stem and faceplate together, creating a highly rigid interface while minimizing the loads on the bolts, making the EA50 perfectly safe for carbon bars.

Race Face took their super popular Turbine 35mm stem and turned the volume up to R. Increased strength to handle the harshest aggressive all mountain riding combined with an update to 0-degree size for optimized fit and performance. This stem sets the new standard in weight vs strength. - CNC Aluminum - 0-degree rise for perfect fit on aggressive bike frames - Extensive CNC machining for weight reduction without impacting strength - TopLock faceplate design for easy and secure installation

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
