The Campagnolo QCK-Tech Bottom Bracket T47x68 is engineered to match the performance standards of the Super Record groupset while ensuring broad compatibility across modern frame designs. Its QCK-Tech system simplifies installation and enhances protection with a patented external seal and a fiberglass-reinforced polyamide central tube, both working to keep out water, mud, and debris. Oversize stainless steel bearings are pressed directly onto the Ultra-Torque semi-axles for increased stiffness and efficient power transfer. Built to maintain consistent performance in demanding conditions, this bottom bracket is a smooth and reliable choice for long-term riding.
