Item # EAS0133

Increased strength, reduced weight.

The Easton EA90 Stem sheds grams for race-minded riders, without sacrificing structural integrity or performance. Its EA90 aluminum tubing is the result of a 3D forging process, yielding Easton's lightest aluminum stem to date.

Looking closely at the stem's faceplate, you'll immediately notice the EA90's Distributed Stress Technology or DST, as referred to by Easton. This technology widens the junction between the faceplate and handlebars where the four bolts clamp down, distributing stress over a wider area for extra peace of mind when you're using lightweight aluminum or carbon fiber handlebars.

Note that this stem comes in two rises, 0 degrees (sometimes referred to as 90 degrees) and +/- 10 degrees (sometimes referred to as 80/100 degrees). The steerer tube's height is 40mm, and two opposing bolts secure it firmly in place to minimize stress. The EA90 comes with a 31.8mm handlebar clamp and 1 1/8th-inch steerer clamp only.

Strong and light.

  • Familiarity: I've put it through the wringer

I previously had the 100mm version then went down to 80mm and finally ended up with a 70mm. Due to the shorter length it is significantly lighter and stiffer than the previous sizes I've used. I have the current 70mm on my 2013 Orbea Occam 29 carbon with Raceface SIXC 785mm low rise bars. It makes the bike handle very well. Easton has had a mixed record for the last few years but when it comes to their stems and bars I can only say good things about them. I don't like their hubs but they know how to make strong and light carbon fiber rims and bars along with strong stems. I can't feel a difference between these and my old Thomson Elite X4 stem only that it's much lighter.

Strong and light.

EA90 Black Zero (90) Degree

Easton EA90 on my CX bike.

EA90 Black Zero (90) Degree

Upgraded my cross/commuter

    Needed a longer stem for my cross cycle that I am using for a commuter through the Fall and Winter months. Getting those extra miles on my legs, saving gas, and loving life. Found the Easton EA90 Stem at a great price here at Huck Easy installation and great looks too. Easton even has the torque settings engraved into the stem. Super customer service at Easton too. They replaced the handle bar bolts for free even after I told them that it was my fault because I over-torqued the original bolts. I did not read the torque numbers and went with the numbers off of my old stem. Lesson learned great customer service at Easton and always read the fine print before assembly.

    what does the first number mean in the...

    what does the first number mean in the options? In other words, 0- vs. 10-?

    That the angle of the stem. So the options are 0 degree (flat) or 10/-10 degree rise/drop. The step is either +/- because it can be mounted either direction.

    Go Easton Young Man

      I just installed my EA90 stem on my bike. The original stem is perfectly good, but was 110 mm. The way to measure if your saddle is installed correctly is to put your elbow against the very front of the nose of your saddle, extend your middle finger which should be in the middle and over your handle bars. When I measured, I surely needed a shorter stem, since my finger was short by inches with the seat moved as forward as possible. I installed the new shorter stem, and my Pinorello FP=3 DuraAce was even more comfortable to ride - I do about 50 miles every other day. Another way to tell if your stem is the right size is to to look down and see if the axle of your front wheel looks as though it is under the handle bars. If it looks like its forward of the bars, you need a shorter the rear of the handle bars you need a longer one. The EA90 is aluminum, but I see no advantage to their carbon copy of this stem...they both weigh the same. The Pinorello stem was a bit more flashy looking, however this Easton is finished very nicely and works well. I will attach my bike computer to it, so it will hardly be visable at all. The bike is a bit twitchy with the shorter stem, however, I will get used to that soon enough.

      Better than carbon version...

        I bought this stem along with the carbon version (EC90) to perform a side-by-side, Pepsi challenge styled comparison (remember those?). I liked this one better. Dimensionally and weight-wise they were identical. "They" say that 4-bolt patterns are better (I am not convinced one way or the other) and this one is 4-bolt. I think the two things that made me choose aluminum was price and style - the white stem looks much better than the black carbon with the upside down logo (when mounted 10 degrees up).
