CAMPAGNOLO QCK-TECH BSA/BSC 68mm external crankcase

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

Its glass-fiber-reinforced polyamide central shaft ensures a perfect seal, preventing any internal contamination. The cups house oversized stainless steel bearings, directly coupled to the Ultra-Torque half-axes solidly integrated into the cranks for maximum rigidity.

The result: a direct, responsive and durable drivetrain, 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.
