Potencia Darimo IX2 Aluminio

The new Darimo IX2AL is the benchmark for lovers of aluminum stems. After dozens of finite element analyses and fatigue tests, we have developed a stem weighing only 82 grams at 100 mm in length. Manufactured from a solid block of 7075 aluminum using precision CNC machining, each stem requires almost two hours of continuous machining to achieve the right surface finishes, optimizing the stiffness-to-weight ratio.

The front panel features an integrated cover with only two screws at the bottom, offering impeccable aesthetics and greater rigidity. We use M4 titanium screws with enlarged heads to prevent damage during assembly.

Thanks to our efforts to achieve an optimized design through computational finite element analysis, our square-circular section power maximizes torsional rigidity and reduces stress by 20% compared to sections that are only square or round. This geometry, combined with efficient force distribution through both bolts, allows for perfect compatibility with carbon fiber handlebars, ensuring uniform load transmission across the carbon surface.

The following image shows a comparison between the different types of cross-section (square → square with rounded edges → round) and how their deformation peaks vary.
