Darimo IX4 Carbon Stem

Unleash featherlight performance with the Darimo IX4, a carbon stem weighing just 74 g in the 100 mm length. Built around an innovative removable carbon face plate, secured by four titanium bolts and four aluminum nuts, the IX4 pairs advanced engineering with genuinely refined aesthetics — available now through Cicli Corsa.

Crafted for Performance

Made from high-modulus unidirectional and bidirectional carbon fabrics, the IX4 balances lightweight construction with real vertical stiffness and torsional rigidity — not a compromise on either front. The carbon face plate adds function as much as it adds a refined finish to your cockpit.

Premium Materials: Carbon, Titanium and Aluminum

Engineered with M4 titanium bolts featuring enlarged heads for even clamping force distribution, paired with anodized 7075-T6 aluminum nuts, the IX4 keeps weight to an absolute minimum without cutting corners on safety or durability.

Natural Carbon Fiber Finish

Available in 3K Gloss, 3K Matte, UD Matte and UD Gloss. Matte finishes carry subtle black logos, Gloss versions show bright white with red details. True to Darimo's philosophy, the IX4 is left with no clear coat or varnish, letting the raw texture of the carbon fiber stand out — small voids may appear as part of the handmade process, making every piece genuinely unique.

Safety Beyond Standards

Exceeding ISO 4210-2 certification, the IX4 is engineered for long-term reliability as much as low weight. Recommended for riders under 90 kg, a reinforced version can be custom-built at no extra cost, for added strength and genuine peace of mind.

Versatility Across Disciplines

Suited to road cycling and cyclocross, the IX4 adapts to multiple riding styles. Available with a 31.8 mm clamp diameter compatible with standard handlebars, lengths from 80 mm to 130 mm, and angles from -6° to -12°, it gives you the range to genuinely fine-tune your fit — pair it with the right spacer setup at the headset to dial in stack precisely.

Engineered Shape: Designed for Stiffness

The IX4's distinctive non-round body is the result of advanced Finite Element Analysis (FEA), delivering a 20% increase in torsional stiffness and reduced stress compared to standard round or square stems.
