The Campagnolo PRO-TECH Bottom Bracket Cups T47x68 (OC21-PRT4768) are engineered with Pro-Tech™ technology, providing top-tier protection for your bottom bracket system. Featuring a patented external sealing gasket, these cups shield the ball bearings from harmful elements like water, mud, and sand, ensuring smooth and consistent performance, even in harsh conditions. The watertight central sleeve, crafted from fiberglass-reinforced polyamide, prevents contamination from the inside.

These T47x68 bottom bracket cups come with oversized external stainless steel bearings that are press-fitted securely onto the two Ultra-Torque™ half-axles. This secure fit, combined with the advanced Pro-Tech™ sealing system, ensures optimal performance in all riding conditions.

The Ekar bottom bracket options offer broad compatibility with a wide range of frames, including both threaded and PressFit cups, making this an ideal choice for cyclists seeking a high-performance, reliable bottom bracket solution.
