Campagnolo QCK-TECH Bottom Bracket BB386
Campagnolo QCK-TECH Bottom Bracket BB386 Info
The Campagnolo QCK-TECH Bottom Bracket BB386 is built around Campagnolo's Ultra-Torque system, housing oversized stainless-steel bearings that mount directly onto the crank semi-axles — a design intended to maximize drivetrain stiffness and minimize flex at the pedaling interface. The aluminum cups and fiberglass-reinforced polyamide central sleeve keep weight to around 52 g while maintaining the rigidity a race-oriented drivetrain demands. A patented external seal shields the bearings from water and contamination, extending service intervals even in poor conditions.
The QCK-TECH installation system is designed for straightforward, accurate assembly — threading that seats correctly and stays put, whether you're building a bike from scratch or swapping components in a workshop. This bottom bracket is compatible with BB386 press-fit frames and Super Record 13 cranksets, with shell dimensions of 86.5 mm width and 46 mm inner diameter to match BB386 EVO specifications precisely.
