Design and dimensioning are impressive, mass and stress concentrations have been farther reduced.
Now it's lighter and even more resistant to abuse. Our new military standard alloy treatments double fatigue strength.
New multiaxial machining allows material shaving where only few years ago was impossible.
When you see it in the flesh, you'll realize it's an absolute performance sculpture.
Once more a leader in design and performance, still with our original 4 bolts design.
Beware! You can find UltraStem copies. None of them will even get close to original UltraStem stiffness and performance.
Fatigue and strength tested, exceeds UNI 10518 safety standards.
