Campagnolo QCK-Tech Bottom Bracket - Campagnolo - OC02-QCKBSA

QCK-Tech is Campagnolo's proprietary technology that integrates a special external seal designed to protect the bottom bracket's ball bearings from external contaminants like water, mud, and sand. This leads to improved bearing longevity and consistent performance, even in adverse conditions.

This QCK-Tech bottom bracket is specifically designed for Campagnolo Super Record cranksets and compatible with Ultra-Torque axle systems. It is not backward compatible with Pro-Tech systems. Always verify compatibility with your specific crankset model.

The QCK-Tech system requires minimal maintenance due to its advanced sealing. Clean the exterior with a damp cloth after riding in dirty conditions. Avoid using high-pressure washers directly on the seals.

The bottom bracket weighs approximately 52 grams.

This bottom bracket is engineered to work seamlessly with Campagnolo Super Record cranksets and Ultra-Torque axles. Using it with other brands may lead to compatibility issues and suboptimal performance.

The QCK-Tech bottom bracket is available in different options to adapt to the main frame standards on the market. You will need to select the specific version that matches your bicycle frame's bottom bracket shell type (e.g., BSA, BB30, PF30).

The structure has been completely redesigned to be more intuitive. This means fewer steps, clearer orientation, and easier alignment of components during the installation process, making it faster and less prone to errors.

Ensure you are using the correct specific tools for Campagnolo Ultra-Torque bottom brackets and that the frame's bottom bracket shell is clean and properly faced. Consult the official Campagnolo installation guide.

While the QCK-Tech system offers excellent protection, contamination can still occur. Inspect the seals for damage. If issues persist, professional servicing or replacement of the bearing seals may be necessary.

Double-check that the bottom bracket cups are fully seated and that the crankset is correctly installed onto the Ultra-Torque axles. Overtightening can also cause drag; ensure all torque specifications are met.

Creaking can be caused by improper installation, insufficient lubrication on threads (if applicable to your specific frame interface), or dirt. Ensure all mounting surfaces are clean and properly torqued. Re-greasing the spindle interface may help.
