Campagnolo Pro-Tech Bottom Bracket The Campagnolo Pro-Tech Bottom Bracket system features the robust double-protection of Pro-Tech™ – a patented external sealing ring design and a resilient central tube preventing the harmful ingress of water, mud and grit from contacting the bearings. The Pro-Tech bottom bracket mates with the external stainless steel bearings – which are attached to the crank arms as an integral unit rather than the BB cups for greater size and easier maintenance access – and sits over a stiff, strong inner axle spindle, delivering smooth performance. The Pro-Tech™ sealing system keeps everything clean and functioning perfectly especially when used in inclement weather conditions and off-road. This system is only compatible with Campagnolo EKAR and Campagnolo Super Record WRL cranksets. A full range of bottom bracket options offer broad compatibility over a full range of threaded and PressFit size applications. Note: Check to make sure that your selection is compatible with your frameset bottom bracket type and crankset configuration. (example variant images of item shown)
