Campagnolo Pro-Tech bearing cup<\/h2>\n

The new Ekar bearing cups are specifically designed for the difficult conditions on all-road and gravel routes.<\/p>\n

It features ProTech\u2122 technology, consisting of a patented outer seal that protects the bearings from damaging water, mud, and sand, and a waterproof, glass-fiber-reinforced polyamide inner sleeve to prevent internal contamination. The new bearing cups are paired with oversized stainless steel outer bearings, which are attached to the two Ultra-Torque\u2122 axle halves that are permanently bonded to the cranks. Thanks to the ProTech\u2122 sealing system, performance is always optimal, no matter where you ride. Ekar bottom bracket options offer broad compatibility with most standard frames thanks to a full range of threaded and PressFit bearing cups.<\/p>\n<\/div>\n

    Technologies used<\/h3>\n

    In this chapter, we explain the technologies that the manufacturer uses in this product.<\/p>\n

    Pro-Tech\u2122<\/b><\/p>\n

    The patented ProTech\u2122 dual-seal technology securely joins the two axle halves within the bottom bracket, protecting the bearings from water and mud ingress and ensuring high performance and durability even in the harshest conditions. The innovative and proven Ultra-Torque\u2122 technology has been developed in a gravel-specific configuration. The Hirth spline of the ProTech\u2122 system features self-centering and self-aligning teeth located at the center of the crank arm, where the ends of the integrated axle halves meet.<\/p>\n

    The axle halves are secured with a single, oversized, protected bolt. Its precise fit can even compensate for the misalignment that some carbon frames may exhibit due to minute manufacturing tolerances. The torque transfer of the ProTech\u2122 crankset is as efficient as that of a single thru-axle and lighter. Furthermore, it is also more durable, as it is better protected than other systems. The oversized stainless steel bearing, located outside the bottom bracket cups on the crank arm, provides maximum stiffness, smoothness, and strength thanks to the increased diameter of the pedal axles.<\/p>\n<\/div>\n
