CAMPAGNOLO QCK-TECH T47A Asymmetric External Bottom Bracket

The CAMPAGNOLO QCK-TECK bottom bracket has been completely redesigned to offer faster, more intuitive and precise installation, thanks to the patented QCK-Tech (Quick Tech) technology. This advanced system integrates an external seal designed to effectively protect the bearings from external elements such as water, mud and sand.

Its glass fibre-reinforced polyamide central axle ensures a perfect seal, preventing any internal contamination. The cups accommodate oversized stainless steel bearings, directly coupled to the Ultra-Torque half-axles firmly integrated into the cranks for maximum rigidity.

The result: direct, responsive and durable power transmission, true to the high-performance DNA of the Super Record 13-speed groupset. The QCK-Tech system guarantees consistent performance, even in the most extreme conditions, and is available in several versions to suit all frame standards.
