3T ARX II Pro Stem 3T ARX II Pro Stem
The engineers at 3T aren't (quite) rocket scientists, but they do seem to recognize a solid design when they've produced one. We're pleased to report that the ARX II Pro Stem's popularity throughout the self-sponsored peloton hasn't escaped their notice, and it returns for another model year with all of its original upgrades to the ARX Pro intact but nothing more besides an updated graphic. With its time-tested 2010 alloy construction and +/- 6 degrees of rise, the ARX II Pro all but guarantees the safety of your cycling ship and all those aboard. The most obvious change from the ARX Pro to the ARX II Pro is that the length of the stem is slightly flattened on the sides. 3T notes that this creates a sleeker profile than the original ARX, but we also notice that it brings the cross section more in line with the squared-off edges of stems like the Integra, which use sharper angles to increase resistance to the torsional flex that can eat up watts while you're pulling on the bars in anger. The face plate's top and bottom have also been trimmed up, bringing the bolts together and reducing both the aerodynamic footprint and the weight -- the ARX II Pro weighs a claimed 5g less than its predecessor at 135g. The stem's hardware marks yet another point of departure, switching from Allen to Torx/star bolts, which is a less immediately obvious difference that, if overlooked, may frustrate the unprepared mechanic. The faceplate attaches with the standard complement of four bolts, but the steerer clamp only uses one, contributing yet more weight savings.

3T ARX II Team Stealth Stem 3T ARX II Team Stealth Stem
There's a time and a place for loud and flashy. Sometimes that place isn't the cockpit of your bike. The 3T ARX Team II Stealth Stem adds a touch of elegance to your cockpit with a subtle, matte black finish that downplays the Team stem's stiff, lightweight performance. The Arx II Team continues the original's tradition of simple, classic construction -- but with a design that drops grams from its already low weight. The ARX Team takes the classic, tubular design of the ARX and further refines it with slightly flattened sides and a sculpted faceplate. The ARX II Team stem's faceplate crimps in tighter at the top and bottom, which results in an ovalized appearance. However, even with the new shape, 3T was still able to retain its hallmark cut-out logo. This generation of the ARX also sees a more precise installation process than previous models. Instead of a traditional four-bolt Allen assembly, the ARX II features a Torx assembly at the faceplate and a single M6 bolt to clamp the stem to the steerer.

3T Arx LTD Stealth Stem 3T Arx LTD Stealth Stem
Satin black is cool. Many of today's top-shelf bikes are designed with a menacing mix of gloss and satin black. To upgrade one of these race-bred rigs with bright, shouty components would defeat the purpose. To hang your handlebar on anything less than the 3T ARX LTD Stealth Stem would be nothing short of sacrilege. The 3T ARX LTD Stealth stem is a perfect match for any 3T handlebars, but they've also made a nod to the practical by making it perfectly compatible with other manufacturers' bars. This is possible because particular attention has been paid to the design of the clamp. Recognizing that modern steerer tubes and handlebars are often made from delicate composite materials, the ARX clamp interface is specifically intended to clamp the handlebar and steerer securely for even the most rugged, Roubaix-like conditions, but gently enough so to ensure that none of the clamped material is compromised. How secure-but-gentle is it' So much so that it's passed the rigorous CEN certification standards test. 3T designs their products from the inside out rather than the outside in. That means that they make use of the natural characteristics of the material in their designs. Composite materials have a grain, like wood, so they're stronger in one plane than another. The key to building strong, light structures using composite material is to tailor the grain of the fibers to line up along the load path. That's why the ARX LTD Stealth stem sports that impossibly sexy unidirectional carbon look rather than a more typical woven appearance.

3T Mountain Team Stem 3T Mountain Team Stem
With its 7075 T6 body and titanium bolts, the Mountain Team Stem is the lightest offering in 3T's off-road line, comparing quite favorably with many road-specific stems. Low weight isn't synonymous with low reliability, though, and the already durable 7075 T6 alloy is made even more resistant to torsional flex with a squared cross section. The wide stem clamping plate further contributes to the stem's stiff reliability.

Easton EA90 Stem Easton EA90 Stem
The Easton EA90 Stem sheds grams for race-minded riders, without sacrificing structural integrity or performance. Its EA90 aluminum tubing is the result of a 3D forging process, yielding Easton's lightest aluminum stem to date. Looking closely at the stem's faceplate, you'll immediately notice the EA90's Distributed Stress Technology or DST, as referred to by Easton. This technology widens the junction between the faceplate and handlebars where the four bolts clamp down, distributing stress over a wider area for extra peace of mind when you're using lightweight aluminum or carbon fiber handlebars. Note that this stem comes in two rises, 0 degrees (sometimes referred to as 90 degrees) and +/- 10 degrees (sometimes referred to as 80/100 degrees). The steerer tube's height is 40mm, and two opposing bolts secure it firmly in place to minimize stress. The EA90 comes with a 31. 8mm handlebar clamp and 1 1/8th-inch steerer clamp only.

ENVE Stem ENVE Stem
If you're finishing off a dream build, consider ENVE's Stem as your final, high-end touch. Weighing in at just about 125 grams, it's among the lightest stems out there, but its stiffness and rigidity are what really make it one of the best all-around. The body of the stem is full carbon fiber, while the faceplate is aluminum, and the hardware titanium. The threads are molded into the stem, rather than having bonded-in inserts, to both save weight and make the stem stronger.

FSA OS-99 Stem FSA OS-99 Stem
Let's get one thing out of the way--the OS-99 Road Stem is the lightest stem that FSA makes, and no, the "7050 aluminum body" isn't a typo. By using a proprietary 3D forging technique and special heat treatment ("witchcraft" is the technical name) FSA makes the OS-99 as strong as a heavyweight stem but as light as a part made of pure carbon fiber. To be fair, the faceplate is built partially from carbon, to achieve the perfect balance of strength and weight, and the unbreakable bolts have been forged from titanium, so the OS-99 isn't pure aluminum. The faceplate also has a serrated surface that will grip both carbon and aluminum bars, and a rise of +/- six degrees, depending on which way you set it up.

FSA SLK Stem FSA SLK Stem
FSA's SL-K Stem was constructed to provide rigid support for the handlebars, feeling similar in both weight and stiffness to carbon and titanium with a precise, CNC-machined aluminum construction. To guarantee rigidity, FSA 3D-forged the aluminum stem body. This process starts with one ingot of aluminum that is bored out and shaped internally. This improves the aluminum's grain structure and eliminates the use of welds for drastically reduced weight. The benefits to you are a heightened stiffness, with weight comparable to carbon fiber, at a considerably lower cost. To maintain the flow of weight savings, the SL-K uses a carbon fiber face plate with chrome-moly hardware. The SL-K features a 40mm fork-clamp stack height with a 6 degree rise. FSA has included clamp-to-clamp model graphics that run inverse of each other to keep the aesthetic unchanged whether you slam the stem or run positive rise. It is only compatible with 1-1/8in steerer tubes and 31. 8mm clamp diameter handlebars.

PRO Tharsis XC Stem PRO Tharsis XC Stem
Given that it shares the corporate family tree with Shimano, it's no surprise that PRO developed cockpit kit that allows for clean, flawless routing of the new XTR Di2. PRO's calling this system Tharsis, and the Tharsis XC Stem is one of the two key ingredients. As PRO's own Bas Schpveld describes it, the Tharsis stem and handlebar combination is a "showcase for Shimano" to demonstrate the possibilities of not only clean shifting and routing, but the simple elegance of a drivetrain and cockpit designed to interface seamlessly. In addition to the internal routing, this interface also involves a clamping system that ditches the usual star nut in favor of a threaded spacer that compresses the stack, leaving the steerer tube free to house a Di2 battery. The internal, intuitive Di2 routing is only part of the Tharsis XC Stem's story, though, as its lightweight alloy and titanium bolts keep the claimed grams under 145 for the 100mm option. It's also stiff enough for XC sprints and durable enough to survive standard trail abuse and the occasional instances when a bike gets a little too intimate with a passing tree. After all, clean lines and stylish routing are useless if the kit wilts at the first sign of trail furniture, and the Tharsis models were developed in conjunction with the riders on Shimano's sponsored XC teams to ensure that their fortitude matches their style.

Race Face Turbine 35mm Stem Race Face Turbine 35mm Stem
35mm handlebars are blowing up, but the necessary stems are a little behind, so Race Face made the Turbine 35mm Stem to give fat-barred rippers a little bit of dap. It's largely the same as the standard Turbine, with a bombproof 7075 aluminum body, a four-bolt clamp, and opposing steerer bolts to provide serious power with causing any damage. It's also angled at six degrees, so you can add a little rise to your bars or lower them a little bit, depending on which way you install it. The only real difference between the classic Turbine and the 35mm is the diameter of clamp which, obviously, has been enlarged to 35mm. Even with the size increase, the Turbine 35mm weighs in under 140g, so it won't slow you down if you're looking to keep things light.

Zipp Service Course SL Stem Zipp Service Course SL Stem
Zipp's entire Service Course line proves that aluminum still has a place in cycling componentry -- it will never be as light as carbon, sure, but it will never be as expensive either, and that's enough of a reason for us to stand behind it. Zipp strikes an admirable balance between cost, weight, and performance with the Service Course SL Alloy Stem, which features a 3D-forged 7075 aluminum construction to give it a mix of superb strength and stiffness inspired by kit built for the peloton. Both stems in the Service Course line are built in the same tooling, with smooth lines and a newly redesigned faceplate with enough negative space to for easy handlebar orientation. Compared to the pedestrian version, the Service Course SL stem drops some grams with CNC-machining and by replacing the stainless steel Torx bolts with titanium.
