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 stem....to 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.
