The new Easton EA70 4-bolt stem is race ready with Easton’s proprietary EA70 alloy, Top-Lock™ technology, DST™ and race proven TaperWall™ technology. The 3D Forged design and shot-peen finish ensures maximum strength and fatigue life. Perfect for the real enthusiast or racer looking for that winning edge.
The EA70 stem was specifically designed with ultra-light, high-performance handlebars in mind. By better distributing the clamping stresses (Distributed Stress Technology-DST™) the EA70 increases performance and longevity of the handlebar.
Carbon-friendly Top-Lock™ Technology significantly improves strength, stiffness and performance by locking down the top of the faceplate of the stem before tightening the bottom bolts, therefore minimizing loads on the bolts.
The EA70 combines proprietary TaperWall technology with high-performance EA70 aluminum alloy for a distinct weight and performance advantage.

TaperWall tubes offer maximum variation in wall thickness. The result is increased strength with reduced weight.
Easton’s ultra-smooth wall transitions transfer impact energy freely down the length of the tube. So shock is dampened without compromising stiffness.
TaperWall multiplexing creates multiple reinforced wall zones — effectively gusseting tubes on the inside. The unprecedented control of Easton TaperWall technology allows each tube to be precision engineered for its specific application.
