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

Whisky's No.7 Stem is a lightweight stem with a clean aesthetic. Stems only have a few jobs to do: hold the bars, provide stable support, and look good. Ours does all three admirably.

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.

Built for all-mountain riding, the new Aeffect Rally 35 stem is a no nonsense workhorse. With increased strength and shorter length options available for modern bike geometry, Aeffect R performs well above its price point…and all of this at a competitive weight.

- Solution for riders wanting to raise their drop bars for added comfort - 225mm tall quill (210mm above the min insertion line) - Forged aluminum - 22.2mm quill - 25.4mm clamp - 386-415g

An adjustable stiffness suspension stem that smooths out the ride by reducing the affects of impacts and road vibrations. - Unwanted vertical movement is absorbed by twin interchangeable elastomers - Stem retains torsional rigidity - Travel is limited to 1-2 centimeters - Made with 6061-T6 Aluminum - Includes 5 swappable elastomers (2 pre-installed, 3 additional) to customize the ride feel for your bike, weight, and riding style

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.

Easton’s lightest aluminum stem is the choice of road racers and top XC pilots alike. The advanced EA90 aluminum tubing and 3D forging process results in a perfect blend of strength and weight.

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
