Easton EA90 0-Degree Stem 2014
Easton's EA90 stem features DST technology which distributes the clamping forces more evenly over a large area. The 3D forging of Easton's EA90 aluminum help makes the stem strong yet lightweight.
I've always considered Easton stems and bars to be highly reputable, functional and light. They are about as light as any stem out there and I have never had any failure or breakage. I also like that the bolts are solid and don't show wear or rust. Thompson's latest stems use smaller allen bolts and I think stripping is potential an issue. I like the looks, but I'd say function is the first priority with these stems and they do it well.
I've been running the 80mm version on my Pivot 429c and and it works great and was lighter than the Thomson I replaced.
