An aerodynamically honed stem with adjustable length and angle to optimize your position. The rider makes up 80-90% of total aero drag, so refining your position can produce some of the biggest gains of all. Further, the shape of the stem, plus the ability to eliminate headset spacers, allows for cleaner airflow at the front of the bike, producing valuable drag reduction. Created in conjunction with Team Dimension Data, the stem delivers the confident and responsive ride feel demanded by the best riders in the world. This stem is intended for negative drop only and cannot be flipped or reversed in a positive rise. - Material: Carbon - Faceplate Material: Aluminum - Hardware Material: Titanium - Stack Height: 42.5mm with length shim / 45.5mm with angle shim - Torque Spec, Face Plate Upper Bolt: 10Nm, Lower Bolt: 6Nm - Torque Spec, Steer Tube: 5.5Nm

When stiffness and weight are the top on your list, you want Ritchey's SuperLogic C-260 Carbon Stem. This revolutionary design starts with a bar clamp that wraps a full 260-degrees around the handlebar to distribute clamping stress evenly through the handlebar, faceplate, hardware and stem body. Ritchey's first full-carbon stem, the C-260 features high-modulus carbon for stellar strength-to-weight ratio that translates into a solid but forgiving ride. And, the steer tube clamp uses three bolts and a curved slot to reduce clamp stress on the steer tube, so you can run carbon bars and a carbon steerer with no problem.

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

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 modulated the Oversized formula to emphasize pedaling stiffness. We have transferred material specifically to sectors that experience sudden stress from pulling up on the handlebars. You’ll feel a difference in your acceleration. These stems are engineered for the larger-sized racers. -Material: 6061-T6 Aluminum -Process: Cold-Forged -Hardware: Chromoly Clamping Bolts -Finish: Anodized w/Laser-Etched Graphics Weight: -48mm: 280 g / 9.8 oz -53mm: 290 g / 10.2 oz
