It is equipped with pro-tech ™ technology which consists of a patented external seal gasket that protects the sphere bearings from the harmful entrance of water, mud and sand and from a central tank tank tank top in polyamide loaded with fiberglass to avoid contaminations from the inside. The new caps mate with the oversized oversize stainless steel caletto beads on the two semi-perisons Ultra-Torque ™ firmly fixed to the pedagles. Thanks to the Pro-Tech ™ seal system, performance is always optimal, however and wherever you go. The options of the Ekar central movement offer a large compatibility with the frames on the market thanks to a complete range of threaded and pressfit caps.

Technology

Pro-tech ™
The patented Pro-Tech ™ double-sequel technology firmly connects the two semi-perni inside the central movement and protects the bearings from the entrance of water and mud, providing high-performance longevity, even in the worst conditions. The innovative and tested Ultra-Torque ™ technology has been developed in a gravel key: the Hirth joint of the Pro-Tech ™ system presents self-decentral and self-employed teeth located in the center of the Pedival where the ends of the integrated semi-serins meet. The pins are fixed together with a single protected oversized vine, their precise coupling may even remedy the misalignment that some carbon frames may have thanks to the tiny differences in tolerance in their manufacture.

The transmission of the pair of the Pro-Tech ™ pedagle system is efficient as that of a unique passing pivot and is lighter. Furthermore, being better protected than other systems, it is also more durable. The oversized stainless steel bearing placed on the pedagple, outside the caps of the central movement, offers maximum rigidity, smoothness and resistance thanks to the increased diameter of the pins.
