Stems

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)

- Forged & blasted 2014 alloy for high strength & fatigue resistance at a reasonable weight - Four bolt bar clamp holds bar securely in position - Interlocking U-Shaped Handlebar Clamp Geometry transferring more load through the stem body and not the bolts - Faceplate eliminates ‘stress risers'

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 newest generation of 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 Garmin mount, known as the ICM system, for cleaner lines and improved aerodynamics (included). Our EA90 stem comes in at 120 grams (100mm). 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. - 3D Forged EA90 Alloy - Easton ICM direct-mount faceplate computer mount compatible - TopLock Design for easy bar installation - EA90 includes Easton ICM Garmin computer mount - Finish: Black Ano - Weight: 120g (100mm) - Rise: +/- 7 degrees - Clamp Diameter: 31.8mm - Steerer: 1 1/8"

All Box stems are engineered and crafted using our Oversized Technology. As we follow the load paths down the handlebars we have focused our attention on the stem-to-bar interface. Since the Oversized handlebars have an increased wall thickness and tube diameter in this sector we have reciprocated with an augmented stem interface with greater surface area. We’ve done this by moving material from low stress areas. This has greatly minimized twist and contributed to responsiveness. As the stem in mated with the handlebars we have contributed to increased pedaling stiffness by providing a backstop to the “lifting” phenomenon. There is no point pushing hard on your pedals if you can’t pull up on your handlebars and deliver that power. Power can easily be lost to handlebar-to-stem deflection and the consequences can be poor power delivery and steering control. When combined with Box’s other Oversized components, you’ll experience heightened responsiveness and reduced latency. Key differences: In this particular model stem we’ve tailored the Oversized strategy to favor utility and access. The geometry has been altered to allow for easy handlebar removal while at the same time scavenging material from low stress zones. Ideal for those who don’t want to compromise on user experience to gain performance. These stems are engineered for the larger-sized racers.

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.

Renthal's revolutionary Integra 35 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.

Key differences: This particular model stem pushes our Oversized Technology to the extreme as it maximizes the shift of material from low stress zones to the Oversized interface. These stems are engineered for the smaller-sized racers. -Lightweight 3D Hollow Design -Front-Load Clamp Design to Fight Pull-Up Forces -Large Bar Bore -Large Hollow Clamping Bolts -Superior Strength

Hollow stems are cold forged from the highest quality 6061-T6 aluminum available. Featuring an open skeletal design and a dual mid-bolt wedge mounting system, they are lightweight yet maintain a very high level of strength. A 53mm extension stem weighs just 218 grams/7.7 ounces. By removing the rear pinch bolts and moving the mounting bolts to the middle of the stem, we reduced the weight and size and eliminated a serious hazard to the rider’s knees. These stems come with either a 48- or 53mm extension and a 22.2mm bar bore. To ensure proper clamping force, the stem must be mounted on a fork with at least 45mm of exposed steerer tube. Not compatible with forks that have carbon fiber steerer tubes.
