Campagnolo QCK-Tech Bottom Bracket

The performance level of the Super Record groupset is delivered according to different bottom bracket configurations, designed to perfectly integrate with any type of frame, without compromising efficiency and performance.The new Super Record bottom bracket has been redesigned from scratch to provide faster, more intuitive and more precise assembly, thanks to the proprietary QCK-Tech (Quick Tech) technology. This advanced system integrates a patented external seal, designed to effectively protect the ball bearings from external agents such as water, mud and sand. The central tube, made of polyamide reinforced with fiberglass, guarantees impeccable watertightness, preventing any contamination inside. The new cups house oversize stainless steel bearings, fitted directly onto the Ultra-Torque semi-axles, firmly integrated into the cranks. The result is superior structural rigidity and direct, reactive power transmission faithful to the high-performance DNA of the Super Record groupset.Tha
