Stems need to be strong, durable, and light, and it mustn't crush the handlebar and fork clamped on either end. Easton addresses all of those details with its updated EA90 Stem that's a larger diameter and finished in a lovely Black anodization that's sure to look great on any bike. Furthermore, it includes its integrated mount for Garmin computers offering cleaner lines and better aerodynamics.
The most unique feature of the EA90 is the DST technology faceplate. Distributed Stress Technology is simple, but works wonders. It better distributes clamping forces more evenly over a larger area, making it ideal for lightweight aluminum and carbon handlebars. On traditional stems, the clamp itself can create stress at its edges and tightening the bolts increases this. The EA90 has a carefully designed faceplate and stem recess as well as its 4-bolt location so those stresses are better distributed over a wider area to lessen force spikes on the handlebar.
The stem is constructed from aluminum tubing and receives a 3D forging process for the ideal blend of strength and weight. It comes in two different rises, 0 and +/- 7-degrees and the steerer clamp is secured by two opposing bolts to minimize stresses on the steerer tube. It uses a 31.8mm handlebar clamp diameter and is compatible with and 1-1/8-inch steerer tubes. Lengths are available between 70-120mm in 10mm increments.
