The newly designed Ekar bottom bracket is tailor - made for the tough demands of all - road and gravel cycling and racing. It has a powerful double - protection system with an external sealing ring and a fiberglass polyamide central tube. This setup effectively keeps out water, mud, and grit, reducing potential damage. The bottom bracket works with external stainless steel bearings attached to the crank arms as one unit, not the BB cups. This design makes it larger and easier to maintain. It sits on a rigid inner axle spindle, providing smooth, fluid, and consistent performance right from the start. Thanks to the ProTech sealing system, it maintains top - notch performance regardless of where and how you ride. The Ekar bottom bracket offers wide compatibility for both threaded and PressFit applications. The patented dual - sealing ProTech technology securely connects the two semi - axles inside the bracket and shields the BB bearings from water and mud, ensuring long - lasting high performance, even in the harshest conditions. It's an innovative gravel - focused upgrade from Campagnolo's Ultra - Torque technology. The ProTech system's central Hirth joint has self - centering and self - aligning frontal teeth at the crank's center where the integrated semi - axles meet. The axles are fixed with a single, protected oversized bolt. Their precise fit can even correct minor misalignments in some carbon frames due to manufacturing tolerances. The ProTech crank system transfers torque as efficiently as a single - piece axle, is lighter, and more durable because of better protection. Oversized stainless steel bearings on the crank, outside the BB shell, offer maximum smoothness and strength due to the increased axle diameter. Specification: Ekar - specific BB cups, for use with external stainless steel bearings on the cranks, alloy construction, weighs 50g, and features a strong fibreglass - polyamide tube.
Using the Campagnolo Ekar Pro - Tech bottom bracket is straightforward. First, make sure your bike is compatible with the Ekar bottom bracket. It works well with both threaded and PressFit applications. Attach the external stainless steel bearings to the crank arms as an integral unit. Then, fit the bottom bracket over the inner axle spindle. When riding, you'll enjoy smooth and consistent performance, no matter the terrain. As for maintenance, after each ride, especially in wet or muddy conditions, clean the bottom bracket to remove any dirt, water, or grit. This will help keep the ProTech sealing system working effectively. Periodically check the single, protected oversized bolt that fixes the axles. Make sure it's tight, but don't over - tighten it. If you notice any unusual noise or reduced performance, it might be time to have a professional take a look. With proper care, your Ekar Pro - Tech bottom bracket will serve you well for a long time.
