The Darimo IX2 Stem serves as a critical connection point between the bicycle's fork steerer tube and the handlebar, allowing the rider to steer the bicycle. Its design focuses on providing a secure and rigid connection while minimizing weight through the use of carbon fiber. The stem is engineered to meet and exceed standard safety tests (EN ISO 4210), ensuring reliability under normal riding conditions.

• Road Handlebar (Darimo Ellipse): Specific installation procedure. Fork Head Tube Compatibility: Requires a diameter of 28.6mm. Minimum Head Tube Length for Installation: 43mm.
