Bicycle Stems

Easton Haven Stem - Easton Haven Stem 2014. The Easton Haven stem is an all mountain game changer. The Haven stem is a 143g (70mm) stem that’s fully CNC machined from one block of aluminum creating the highest stiffness-to-weight ratio of any Easton stem ever made, which you’ll greatly appreciate as you torque your bars climbing to the top of the mountain. Distributed Stress and Top Lock Technologies optimize the bar to stem interface by removing stress risers and eliminating rocking caused by floating face plates.2014 Easton Haven Stem Features.

Easton EC90 SL Stem - Easton EC90 SL Stem 2014. The EC90 SL stem is the lightest, most durable stem in the world that can handle years of abuse. Easton not only wanted to make an extremely light stem (just over 100g for the 100mm model), but they wanted a stem that could handle the cobble-stone roads of the Paris-Roubaix. In fact, the EC90 SL is so strong it could handle cyclocross or XC racing as well.

Easton Havoc Stem - You gotta love that the Easton Havoc Stemis CNC machined from a solid block of aluminum. That's gonna give you some serious steering confidence. But sheer mass alone isn't the Easton modus operandi. They've also built in a bit of science -- even if that's the farthest thing from your mind as you gap a rock garden and dive for the next wall ride. Eye up the Havoc Stem nose-first, from the face plate back toward the steerer, and you can see their first trick.

Easton EA90 Stem - We all want stems that are strong and light. We want them to be durable, and we want them to minimize stress on the handlebar and fork clamped on either end of the stem. Easton addresses all points in their EA90 stem. The most unique feature of the EA90 is the DST technology faceplate. Distributed Stress Technology is simple, but works wonders. It appears to be just a flourish; notice how the "E" icon spreads past the four bolts on both sides.

Niner RDO Stem - It's pretty amazing what manufacturers are able to do with aluminum these days. 180 grams used to be lightweight for a stem. Now that would be a pig. And don't think that strength has been sacrificed–these new stems are strong enough to handle anything that modern freeriders can throw at them. The Niner RDO Stem is a perfect example of intelligent design at work. Niner put the right material in the right places for a stem that weighs an incredible 115 grams–and that's the 110mm length.

FSA OS-99 CSI Stem - The 20-words-or-less summary is easy to do: The FSA OS-99 CSI stem is an FSA OS-99 stem wrapped in carbon fiber. But there are nuances to it that require elaboration: For starters, this is different than most other wrapped carbon fiber stems we've seen. It's much lighter than those stems. For the older wrapped stems, manufacturers were generally taking their heaviest stem, wrapping some cloth around it and clear coating the thing.

FSA SL-K Carbon Stem - We keep seeing more and more of the pro peloton reverting back to the tried and true reliability of aluminum stems, and the FSA SL-K Carbon Stem makes a good argument for why. Pairing the latest in alloy forging technology with lightweight carbon fiber, the SL-K Carbon improves on past without abandoning the future. With a foot on each side of the line, FSA provides a stiff support for the handlebars at a weight that's in line with carbon and titanium.

Thomson X4 Stem - The Thomson X4 Stem is stronger and lighter than their older Elite stem. A good part of this weight savings comes from the change in design. Where the Elite used an internal wedge clamp, this X4 relies on a more traditional split clamp for the steerer interface. While it meant losing the knee-saving shape on the Elite, the clamp bolts are pretty minimal given the sculpted design. The Thomson X4 Stem is CNC machined from 7000 series aluminum alloy.

3T ARX Team Alloy Stem - The 3T ARX Team stem is built to balance competing factors: It needs to be light, it needs to be stiff, and it needs to be immensely durable. Perhaps it's no surprise, then, that Arx is Latin for stronghold. Durability is its greatest quality. The ARX Team is forged to give its aluminum grain structure optimal strength. The steerer and bar clamp are beefed up but carefully designed to minimize stress on your fork steerer tube and handlebar (whether they're carbon or not).

Easton EA70 Stem - Easton EA70 Stem 2014. The EA70 stem is strong enough for mountain use yet light enough for your road racer. The Easton EA70 stem is offered in several different lengths and rises to truly dial in your ride. The EA70 stem features Easton’s patented TopLock™ and DST™ technologies, which distributes clamping forces more evenly over a larger range (perfect for light weight aluminum and carbon fiber handlebars).2014 Easton EA70 Stem Features.

Niner YAWYD Top Cap - Do you ever get about halfway up a climb and feel like your legs are about to give out? Would it help to have a little extra motivation? That picture of your girlfriend won't do it. The recording of your father explaining what a disappointment you are won't help, either. What you need is a reminder of the reward that awaits at the end of your ride–a delicious, frothy beverage.

3T ARX II Team Stem - Launched in 2007, the original 3T ARX stem appears on virtually every genre of bike from road to mountain. A strong, versatile stem, the ARX doesn't fall prey to gimmicks. Now, the evolution of the popular ARX stem takes form in the ARX II Team. It takes the classic, tubular design of the ARX and sculpts it with slightly flattened sides and a refined faceplate. The ARX II Team stem's faceplate crimps in tighter at the top and bottom, which results in an ovalized appearance.

Ritchey WCS C-260 Stem - Alloy cockpits are preferred by many riders in the pro peloton because they inspire greater confidence in the event of a crash or impact, despite the slight weight penalties typically associated with alloy. Stiffness and vibration dampening are usually alloy's greatest nemeses, but with its WCS C-260 Stem, Ritchey has created a more compelling case for alloy. The WCS C-260 is a stem that is not only a full twenty or thirty grams lighter than the lightest alloy stems -- as well as many carbon fiber stems offered by most competitors -- it's also significantly stiffer as well.

Ritchey WCS Trail Stem - We can't think of a person whose influence on mountain biking has been further reaching than that of Tom Ritchey. Undeniably, though, mountain bike technology has come a long way since Tom built the first production mountain bikes. However, this isn't to say that Ritchey hasn't played an integral role in this advancement. Case in point is the Ritchey WCS Trail Stem. In the past five years, handlebar width has grown dramatically.

3T ARX II Pro Alloy Stem - 3T garnered a strong following with its original ARX alloy stem lineup, which is why it decided to use the same design platform for its new ARX II. We feel it was a smart move on the Italian component manufacturer's part, as the new stem brings everything we loved from the previous model and threw in some updated features. With the ARX II, the faceplate has been drawn in tighter at the top and bottom in comparison with the original ARX.

3T Integra LTD - As frame engineers continue to refine and rework their road frames and forks in order to build more aerodynamic machines, so too are component manufacturers going back to the drawing board in search of more efficient, wind-cheating designs. While we all know that the more accessories we bolt on and attach to our machines decreases our overall aerodynamics, there are certain components that have become staples on our bikes. You know exactly what we're referring to: those bulbous, unsightly computers that stand out like sails in the wind on our bars and stems.

3T ARX limited Stem - The 3T ARX LTD 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.

3T ARX Pro Alloy Stem - The 3T ARX Pro stem is identical in almost every way to the ARX Team stem. In fact there are only 3 differences of note: (1) The ARX Pro uses a steel bolt package instead of the Team's titanium bolts. This results in a net weight difference of 30g, with the ARX Pro weighing in at 150g. (2) The Pro is available in only one rise: +/- 6° (aka 84°). (3) The Pro has a White stripe down the side.

Deda Zero100 Stem - The standard Deda Zero100 Stem is identical in nearly every detail to the Zero100 Servizio Corse. It's made with the same ultra-light 2014 aluminum alloy construction and with the same 3D forging to maximize the wall thinness (and thereby shave weight). The only distinction, in fact, is that the Zero100 foregoes the titanium bolts that come standard on the Servizio Corse model. Instead, it has stainless steel bolts. For this slight hardware modification, you save nearly 50% in cost.

Easton Havoc 35 Direct Mount Stem - The Easton Havoc 35 Direct Mount Stem is truly a three-trick pony. Boasting ridiculous strength (yes, that’s EA90 aluminum), unheard-of light weight (just a hair over 100 grams), and Easton’s new, innovative 35mm clamp, the Havoc 35 is going to be showing up on gravity-fed badasses’ bikes everywhere. So, the insane strength and light weight are pretty self-explanatory. Here’s the story behind the clamp. The friendly folks at Easton noted that handlebars, especially DH bars, were getting wider and wider and nothing was being done to alleviate the added stress caused by the increasing leverage ratios. 26.8mm clamps were fine when handlebars were...

Easton Havoc 35 Stem - Easton Havoc 35 Stem 2014. The Havoc 35 line was made for riders who go bigger than current all-mountain products can handle. By borrowing from their experience in motocross bar design, Easton’s beefed up the handlebar clamp diameter to 35mm to provide a much stronger, stiffer, and more secure handle on the bars. Constructed of fully CNC machined EA90 grade aluminum the Easton Havoc 35 stem features Top Lock Technology™ and Distributed Stress Technology™ to remove stress risers and eliminate rocking caused by floating faceplates.2014 Easton Havoc 35 Stem Features.35mm bar clamp, 50mm length, 0° rise, 1 1/8" steerer clamp100% CNC machined from one block...

Easton Havoc Bolt-On Stem - Like the Easton Havoc Stem, Easton's Havoc Bolt-On Stem is CNC milled from a solid block of metal and is a thing of beauty. Also, it's a thing of precise function, designed to sync happily with a triple-crown fork and steer World Champion racers to victory. No less importantly, it's designed to let you ride within the tape or out of bounds with more control and more safety. The latter comes into play because Easton deploys Top Lock technology, which literally locks the face plate to the Havoc Bolt-On Stem so it cannot shift.

Enve Stem - We always raise an eyebrow when we hear that a stem can be used for either road and mountain, but it would appear that the Enve Stem has managed to pull it off with elegance. With a design so beautiful that it warrants white gloves for handling, the Enve Stem is durable enough for dirt and light enough for asphalt. The perfect accompaniment to any Enve handlebar, the Enve Stem is the only stem Enve makes, because it does it all.

Niner Alloy Stem - With carbon fiber getting all the buzz these days (actually, for about the last 15 years), it's easy to forget just how good aluminum is. It's stiff, lightweight, inexpensive, and best of all, reliable. Especially when you're talking about components like handlebars and stems. The Niner Alloy Stem takes advantage of all these qualities while keeping costs and weight to a minimum. A high-quality stem is a great upgrade for any bike.
