Easton’s new EA50 4-bolt is a value-added performance stem with features such as new Top-Lock™ technology, DST™ and proven TaperWall™ technology. The 3D Forged design ensures maximum strength, while the shot-peen finish provides great fatigue life. Perfect for the recreational racer looking for performance, strength and reliability.

By better distributing the clamping stresses on the bar, Easton’s design greatly reduces peak stress areas—reducing the chance of bar failure under load. Easton does extensive testing of its own products as well as those of its competitors. Through this testing, Easton’s EA50 stem with DST design has been shown to be markedly superior at protecting lightweight, high-performance handlebars.

Great fit and interface between the handlebar and stem is crucial. Traditional 2-bolt and even 4-bolt designs still allow loads to place extra stress on the bolts, which intern will twist and eventually fatigue.
While working with our test lab technicians, Easton engineers found that by locking down the top of the faceplate of the stem before tightening the bottom bolts allows the stem and handlebar interface to tighten, offering better load transfer more efficiently while minimizing loads on the bolts.
Top-Lock™ Technology significantly improves strength, stiffness and performance.

Through the years, Easton has developed and refined a process of cold-working aluminum that sets the standard in the industry. TaperWall technology infuses our tubing with the unique performance characteristics revered by cycling enthusiasts and world-class athletes alike. Our computer-modulated draw benches allow us to create multiple tapers in the same tube, so the tube walls can be reinforced anywhere along their length with incredible precision. The result is jeweler-smooth walls that eliminate the stress points typical of other manufacturer’s tubing. Strength, weight, fatigue life, and responsiveness are all enhanced.
