THE ULTIMATE DOWNHILL STEM. The EM90 dampens high-frequency vibrations that contribute to hand fatigue. At a mere 160 grams this stem delivers comfort and performance.
Design Objective: Design a stem that takes advantage of magnesium’s light weight and inherent vibration damping properties.
Material Choice: In order to get the lightest and strongest stem in the world, you have to use materials and engineering that no one else in the world can! MG60 and EM90 magnesium stems feature proprietary alloys, design, and manufacturing techniques.
The Technical Challenge: Special care must be taken in machining magnesium. Also, great lengths must be taken to protect it from the elements.
What should you look for? In a stem, stiffness, weight, fatigue and impact strength are paramount. The better you can achieve these goals, the higher the performance you get. The catch is, there are trade offs. When you reduce the weight, you lose stiffness and strength—and fatigue life goes out the window.
The Starting Line: Using custom-designed test machines, we measured the stiffness, strength and fatigue life of competitive components.
The Finish Line: We developed the first commercially available magnesium stem. We created a stem that is lighter, stronger and has greater fatigue strength and vibration damping.
Rider Benefits
• Less weight means less work.
• Better vibration damping means more control and comfort.
• Increased strength means the stem will survive the hard knocks.
• Better fatigue life means the stem will last longer.
